Is there a higher value for the first design calipers? A friend called to ask me and I really don't know, I think they changed in '67?

Gary:
I agree with Joe's post....................but I would also say that they ARE WORTH more to someone who has the early cars. These castings are difficult to find anymore. Although the casting numbers are not judgeable at this time, I believe that someone who does a high dollar restoration ($$$$$$) would want to have the proper brake castings on the car if he can get them.
That being said, I would think that 2X the $$ going exchange rate for the typical/later design cores would probably be a good ballpark number to use.

Re: '65 caliper cores
I have 1 front and 1 rear early style calipers, with the bakelite insulators on the pistons, VERY RUSTY been in my basement for about 45 years.Comment

Larry------
As far as first design casting numbers go, there are probably a lot out there in "Corvette Land". However, as far as first design calipers which still have the first design internal configuration, I expect there are not a lot left. In the early days of Corvette brake caliper rebuilding, it was routine for caliper rebuilders to machine out the piston guides and convert first design calipers to second design. Unfortunately, the early days of Corvette caliper rebuilding is exactly when a lot of 1965-E67 Corvette calipers needed to be rebuilt. So, I would expect that first design calipers "suffered mightily" at the hands of the rebuilders' Bridgeport machines. At that time no one cared about maintaining first design configuration and first design pistons were not available so conversion to second design was the only way to save a caliper from the scrap pile.
Even today, caliper rebuilders routinely machine out the first design piston guides since the VAST majority of customers don't want or care about first design internal configuration.In Appreciation of John HinckleyComment

Also the early design calipers used a castle type head bolt, see;

Re: '65 caliper cores
Thanks guys. I saw these today on E**y. Seems expensive to me but then I use the plain old SS lined lip seal calipers and they are available everywhere.
I will tell him your thoughts and suggest he sell or store them since all he really needs are 2nd design calipers.

Re: '65 caliper cores
I have a original set of 546 calipers with the piston guide machined out for the second design pistons. How much extra do the first design pistons and machine work cost and what's the gain over the second design?Comment

Ralph sent me these pictures to post. I am struggling with a new iPhone and new laptop computer with Windows 8. Damned new technology. I used to only be mad at Bill Gates. Now I can add the Steves -- Jobs and Wazniak to the list. Ralph is coming up too. Ralph you will have to learn how to do this yourself. Get an adolescent, talk to them nicely regardless of how hard that is. Instructions are at:

Re: '65 caliper cores
How do they refinish the bores on these calipers. What method is used??Comment

Re: '65 caliper cores
My 2 cents, stick to the originals, avoid the guys that burn out the inners and convert them to hybrids, like o rings too.
those bolt heads are called place bolts btw...Comment

Re: '65 caliper cores
The ones I've seen done is machine the cast iron bore, then press in the stainless sleeve, then bore and finish machine the sleeve. The sleeve needs to be pressed in the caliper prior to finish machining or else the bore size and shape will change. I heard of shrink fitting too where they heat the caliper and freeze the stainless sleeve.
But the same end results is a rust resistant bore that is quite a bit more wear resistant than cast iron.Comment
