i recently purchased a 68 camaro in the middle of front disk changeover.i was told it was 68 z 28 front disk brakes when i purchased new calibers they did not match up.i have since learned the 67 rotor dimensions match the ones on the car.i know they are camaro because in the last super chevy mag. they showed a sub frame restoe but did not specify 67 68 or 69.in the picture they match what i got.the hubs and rotors that are on my car bolt togetether and the rotor dimensions are 11 inches by 1 inch.any help would be appreciated.

What is the question?
All first gen Camaro rotors are the same 11" X 1" except the 1969 JL8 four wheel disc option, which used Corvette 11 3/4" X 1 1/4" rotors.
67 and 68 used a four piston caliper, 69 without JL8 used a single piston caliper.

the 67 and 68 front disk brakes are different in the 68 dimensions for the rotor are 11 1/4 inches diameter and 1 1/4 thick. plus they are also the slide on type of rotor.the ones on my car best i can tell are 67.what i need to know is if the 67 hud and rotor bolted together?68 was a slide on rotor.

Always fun picking up someone else's project, eh? You never know what you might find.

67 and 68 original disc front brakes are identical. The rotors and hubs are 2 separate pieces bolted together. The calipers are huge and heavy with 4 pistons and they bolted in place around the rotor.

In 69, GM changed to a ----------- a single piston "floating" caliper.
[Edited: I said GM changed to the 1-piece rotor/hub in 69 -- Thanks to David Pozzi for correcting this! They switched in 70]

It sounds like you have a mix of the two. Or perhaps you have 4-piston calipers for a different GM car, like a Corvette or Chevelle.

67,68, and 69 used the SAME two piece hub and rotor, no difference, The rotor bolts to the back of the hub.

67 and 68 use the four piston caliper. 69 used the single piston caliper.

The one piece hub and rotor was not used by GM until 1970. It is not interchangeable with 70 up Camaro rotors because GM changed the spindle.
There are one piece rotor/hubs that were used on Monte Carlo and others that fit the first gen spindle.
You can buy aftermarket rotors that will work with the four piston 67-68 calipers.

What type caliper do you have? is it a single piston or four piston caliper?

What type caliper mounting brackets?

The only slip over rotor I can think of is a Corvette rotor and they are 11 3/4" OD and 1 1/4" thick. Maybe someone cut one down to 11 1/4" and used a truck caliper, the 1" wide caliper and 1 1/4" caliper are interchangeable.
Not a bad idea!
Below is a photo (starting far left, clockwise) of a one piece 11" X 1" rotor on a Camaro spindle, a Corvette 11 3/4" X 1 1/4"rotor a 69 single piston spindle and caliper bracket, and a 69 two piece rotor, 11" X 1".

What you need is a good pair of 11 X 1" rotors and a single piston caliper bracket and calipers. Make shure you have the Camaro disc brake spindles with the short upper mounting boss, not the drum spindle. If you don't you can get yours machined to fit, see my web page for info.
You need the spindle on the left.

i am sure that i have the 4 piston caliber bracket.can i simple buy a single piston caliber bracket at the store to swape and use a single piston?if not does a chevelle 4 piston caliber match up or work with what i have with out having to make any changes?

You can buy a caliper bracket from a Camaro restoration catalog. Or from Master power brake co.
You can buy the single piston calipers from them too, or get them from the local parts house rebuilt, and just pay the core charge as you have no cores to trade in. I believe the core charge is not very much to make it worth it to go out and buy cores at a junkyard.

If you have the disc brake spindles and rotors, you are half way there.

Sorry for bustin in,

O.K., Pozzi, Come clean, I know you got an idea on what big car spindle we can put on our cars to keep from buying custom spindles or spindle extenders. pdq67

Ps. You gota know after a list of stuff like that HA!, HA!

I mailed Late great Chevys a letter tonight asking Danny, the Pres. about the spindles on the Z-16 Chevelle. I will post his reply.

pdq67,
From what I've seen the older cars spindles were like the mid 60's Corvette and 50's chevy. They have the lower balljoint stud pointing down and the spindle goes below the lower A frame, not like a Camaro.
You'd need a spindle that looks like the Camaro one with a bolt on steering arm so you could swap your existing Camaro arm to it.

There WAS a GM supplied taller spindle for Trans Am racing. A friend of mine bought a pair from Guldstrand, but they are not available anymore.

I have a single spindle off an 68 Olds 88. It looks just like the Camaro spindle but bigger. It is 1.5" taller. The bolt on arm is bigger and you would have to stretch the Camaro arm to fit the spacing. The spindle is bigger in the bearing area so you would need a bigger hub too.
The tapers where the ball joints go are larger and would have to be sleeved.

I read somewhere that a C4 Corvette spindle might fit. I don't know about the steering arm part of it.

It might be that a 1/2 ton Chevy pickup from 1970 might be close.
Here's a photo of one that looks just like a camaro spindle but taller with a bolt on steering arm.

I haven't seen one that would just bolt in yet!

David,

Thanks for taking my post in good faith.

The Olds spindle is just what I'm talking about. I've never looked at the up-side-down ball joint GM spindles arrangement even though I owned a '52 Chevy five passenger post and my crippled buddy had a '58 Vette.

I'm wondering if it would be possible to get an Olds brake drum hub (if one exists) and turn its OD down to fit the Corvette rotors, then come up with a bolt on steering arm that would fit a Camaro outer tie-rod end (or even a custom tie-rod adjustment sleeve). I'm thinking that it wouldn't be to difficult to modify the A-arms to use the Olds ball joints.

We would have a heavi-duty, tall spindled, disk brake front end for our F bodies, Chevelles and Nova's and such. And we have a 50/50 chance of the bearing axle shaft being lowered as compared to a Camaro.

One last point would be to find someone that uses Camaro Tech Forum and would happen to have a suspension computer simulation program to run the "as installed" conversion through to check how everything would work (theoretically).

What do you think, if Kyle Tucker is following this, we might have that person, plus help him out.

Come on guy's, lets "read" some comments. pdq67

I hesitated to mention the Olds spindle because they only used it for one year as far as I can tell.
But it's a dead ringer for the Camaro spindle, except bigger.
The pickup spindle looks promising. And the site I found it on makes a 2 1/2" drop version. But I believe it's too much drop. The brakes would be larger too. Probably 11" by 1 1/4" AND they make a 4 3/4" version!

Take a look here. http://www.classicperform.com/discdrop.htm

I'm not shure the steering axis inclination is enough on these spindles.
I think it would be easier to get one of these companies to make a custom spindle.

The Stock Car Products racing spindle is another neat option. It has a removeable lower steering arm which doubles as a lower ball joint mount.
It is 1.5" taller and can be ordered with willwood caliper mounts.
The balljoint holes are probably too large but could be bushed.

The main problem is the steering arm is too long for good steering geometery.
Here is a shot of my 69 Camaro vintage racer with Stock car spindle.
