help please
everything I read indicates that a factory 396 ss car had 12 bolt with multi leaf springs. according to national parts depot catalog 396 was only available with mono leaf springs. does anyone know what it is supposed to be. thanks in advance

NPD is correct if you are just talking about a '67.

this is a 68 model year.

All '68 SS or Z/28 cars should have multi-leaf springs.

this is what I thought. if you refer to npd parts and eaton detroit springs there is no option for a 1968 396 camaro multi leaf spring. is this a mistake on there part.

I have seen '68 big blocks with single leaf springs. I helped a couple of friends install Hijackers on one back in 1970. I think they had to have the F41 suspension option to have multi leafs. It was a 396/325 model with a 4 speed and a 10 bolt diff. and drum brakes all around. All original factory stock. It was bought new at the local dealer, off the lot not a special order. Unless the dealer had special ordered it and had gotten stuck with it.

I remember because we compared that car to my '68 Z parked next to it. They were both Lemans blue with blue interior. Of course mine had white stripes but no spoilers

Well not one survivor mono-leaf 68 BB SS has made it into the CRG database or they would not be reporting all '68 SS', big block or small came with multi-leafs...

this car also has a 10 bolt rearend. in my previous post we where concerned about the authenticity of the being a ture ss big block. my understanding is that the origanol bb parital vin matches the cars vin. now the idea was to correct the rearend and springs however npd and eaton springs only offer mono leafs for 396 application in 1968. please help.

Jason - I have read most of your other posts and it seems you are taking liberty with the info provided you and trying to turn this car into a real big block SS. Now you are claiming the cars orig BB VIN matched the car!! Maybe I'm mis-understanding you but the facts as I see them are that you have a small block AC car that came with a 10 bolt mono-leaf rearend.

Now if you want to transplant a big block, 12 bolt and multi-leaf have at it. Just don't pass it off as a real factory big block. Looking at a Classic Ind catalog they sell a '67-'69 mono for coupe and a mono for the convertible. The sell '67 - '81 4 leaf and '67-'81 5 leaf multi-leaf springs. I have no ideas about why NPD offers what they do shop elsewhere. YearOne a site sponsor has '68 and '69 big block 5 leafs and '68 and '69 small block 5 leafs. My guess is Ground Up (another site sponsor) does too.

Good luck with it, post pic's when you get a chance and enjoy your car!

this is not my car, it is my bosses car. I am restoring a 68rs/ss of my own. Alot of money was paid for this car and I noticed a few things that seemed out of wack if you will. I posted my questions and you guys confirmed my concerns (thanks) when my boss confronted the car builder with the concerns his response (awaiting proof still) the origanol block partial vin matched the cars vin. the machine shop in I believe indiana that took the block in as a core suposedly has the block still and is sending photographs and a rubbing of the casting numbers, date codes and partial vin. the guys response to the monoleaf springs was the npd (eaton) availability and we know that monoleaf's perch is diffrent than multi streghtening his stand that 10 bolt with monos to be correct. I have chevrolet by the numbers and several other camaro restoration books that indicate useage of 12 bolts and multi leafs for all ss cars. i guess i am just a little confused and trying to help someone verify the correctness of his car. I do appreciate all the help you guys have been and do not want anyone upset with me for missusing any information provided.

And I'd be getting that core the machine shop has.....

That was already my suggestion. actually once i started questioning things my first response was why was it sent in. after paying 65k for the car 350 bucks is nothing.

That explains a whole lot... Nobody wants to pay more than twice the value for something and when it happens it's a hard pill to swollow. With you and your boss being in CA labor costs are very high so depending on what the resto shop did to the car and it's starting condition it may be hard to recoupe anything. I have seen a $10k project car roll into the body shop and it cost $30k in body work alone once the car is opened up. After paint there is $50k invested in a very nice car with no drivetrain or interior. Once the interior is done and the drivetrain is gone through, it's only worth $30k on the market. So with that said unless your boss has anything in writing the guy doing the resto most likely has several ways he can arrive at the final cost. You should have your boss go to the CA BAR or at least mention it to the resto guy, those in the auto business here in CA don't like hearing from the BAR. Good luck and keep in mind if that BBC shows up, you can get blocks stamped real easy these days...

I just read the 69 mono/multi thread from CRG. I did not realize that all 350 CI got the multi leaf. If true, that answers a question I have had for a long time. My original motor was gone, and I was curious if it was a 307 or 350. The car still had it's original monoleafs when I bought it, so it must have been a 307.

thought I would post an update on this topic everyone was helpful on determing athenticity or lack there of. car builder now claims machine shop destroyed block and no pictures available (imagine that) 10 bolt date codes to car probably origanol and to top it off the transmison shop who installed the th350 just informed my boss that the car had a pg trany to start. a 12 bolt was purchased from the car builder supposedly date coded for 4500 dollars, geuss what it is a nova 12 bolt that has been modified. 60 some odd thousand for a 30 thousand dollar car. once again thanks all for the great help. I will post the results of the pending law suit.

wow that blows............good luck to you..
