1966 Identification Questions

[Barry J.]

I have uploaded photos of a 1966 Trim Plate, front caliper, A-arm and master cylinder.

It appears to be a April 66 assembly, Blue convertible with Black interior? Correct?

Photo of the master cylinder appears to be a 1967 and not a 66? Could this be J-56 Brake System?

Photo of front brake caliper is different than my 66. The lettering markings are different, anyone know if these are 66 and if so J-56?

The A arms also look to be replacement because they have bolts and not rivets, can anyone confirm?

Thanks a arm.JPGBrake Cal.JPGBrake Cylin.JPGPlate.JPG

Hi Barry:

Was someone using only the front half of the master cylinder? I see just the one brake line. Has the appearance of a 67 but could be something else too. Can you get the number off the side and see if anything is stamped on the flat spot on the front of the cylinder?

The A arms appear to be correct to me but someone has likely drilled out the original rivets and replaced the ball joints.

I look forward to responses from others that can better answer your other questions.

This appears to be a collaboration of many different parts! The caliper appears to have the casting #'s ground off. J56 had dual pin calipers. The caliper reinforcement bracket would also be missing. No power brake - J50 was needed for J56. Some indication on the firewall lets me believe the body is from a '65.

VERY "bubba-ized" car, particularly the master cylinder. This is a 1967+ style master cylinder (although not necessarily from a Corvette application since this same style was also used on other GM vehicles). This style master cylinder was NEVER used on a 1966 Corvette, regardless of brake option. I can also ABSOLUTELY guarantee you that this style master cylinder was never used for an application with a single circuit brake system as is, apparently, the case here. Very, very bogus.

Brake calipers are Delco-Moraine but appear to have the casting numbers ground off as others have observed. I have no idea why this would have been done.

It looks like the upper ball joints have been replaced with non-GM, aftermarket replacements. That's fairly common and not necessarily bad.

I see nothing wrong that $100,000 will not cure

Looks like a standard single-pin caliper. J56 would have two pins.

Re: 1966 Identification Questions

I went to look at the car that years ago appeared to be a nice vette. The car appears to be a 427/390 car, 942 block with IL on the stamp pad it had the correct fan shroud, stabilizer bars have been removed, motor removed, dash was in the attic and couldn't get to it.

With the dash out, motor removed so the car is pretty much stripped anyway I can tell if this car was originally a big block? Was the big block frame different than SB?

The rear end differential and rear springs was also removed.

You are right, 10 years and $100K on this one.

Thanks for the comments......I thought this was going to be a nicer car....

The small block and big block frames for 1966 were, basically, the same. However, the big block frame had weld nuts for the rear stabilizer bar bushing retainers. Small block frames may or may not have had the weld nuts. If the frame has no weld nuts, though, then you KNOW it was not originally a big block.

Look for evidence of a radiator supply tank installation. For 1966 ALL small blocks used a radiator supply tank but NO big blocks used a radiator supply tank.

Re: 1966 Identification Questions

The reason the caliper has the ground spot is because Vette Brakes ground a flat spot to stamp their serial number on when they sleeved the caliper. Notice also the stamped "VB" for Vette Brakes.
