Anybody

Where is the part number located on a 69 split rotor?

Can these be built back up if they have been cut to far?

What is a pair "USED" worth?

What should the min. allowance/mesurement from one surface to the other?

I have never run in to a pair for sale before nor heard of a price paid for a pair.

Any information on the split rotor will be helpfull.

Post here or email be direct please

I don't think anyone sells a replacement bolt on rotor. There are later style one piece replacement hub/rotors available.

Minimum thickness is .965" No way to build them back up that I know of.

If you wanted some bad enough, you could talk to Coleman racing about having some made up. They make custom rotors.
I don't have the answers to the rest of your questions.

You can find them used and NOS every so often on eBay. I bought a set of used on eBay for $75 and only one was good, but that is all I needed. I have seen NOS ones go for about $250 to $300 each. I guess it depends on how "correct" you want your car, otherwise you would have to buy the replacement one piece rotors that are out there.

8ball,

The guy that gave me (1) two piece hub had a good rotor on it, AND I mean almost like NEW!!

"David gave me a second hub but no rotor..)

What will you give for it plus shipping and I will look up in my e-mail list for who gave it to me and split the money with him...

(I hate ta say it but my poor old memory is just about as long as my left-hand index finger nowadays!!!)

E-mail me at home and I will get back to you..

how much metal do the cut away on the rotor when it gets turned? i have two that are at .999 will i still be within specs when they get turned?

thanks

There are places that do metal spray, maybe that would work to build them up but I don't know if it would last. Most metal spray powder for cast iron has a lot of nickel used as a binder and it probably wouldnt work as a braking surface.

I've seen custom rotors made but I think they were all non-vented for vintage race cars.

at .999 i would bet they would still be above discard. probably even still above their 'machine to' spec. you wont know for sure until they are cut.

if they were mine i would not cut unless there is no way mere sanding would help. if i did have to have them cut, i would have them cut with an 'on-car' lathe.

.965" is minimum thickness. I wouldn't machine them unless there is runout. If the rotor had some little grooves, I think I'd leave it alone unless there were braking problems.
