That was a terrific find Mike.
Your sharing is very much appreciated!

That's a cool find Jon.
Will that cap be used on the Johnny Moore Camaro?

Hi Mike,
    Those pieces compose the adjustable bearing spacer. They allow the bearings to be fully snugged up, but yet have minimal preload, thus drag. In other words, less friction. You can actually feel the difference pushing the car back and forth in the shop.

As the bearings are still side loaded in the corners, the benefits likely are mostly in the straights. I suspect they add some minimal stiffening to the spindles as well. The bottom line is they free up some horsepower which should help in the acceleration. They definitely reduce the bearing temperatures. Taking into account the small bearings we have on the early Camaros, it all helps.

The car was set up very professionally for a privateer, and even had bearing spacers in the front. For this reason, I'm hesitant to discount their usefulness. Any ideas?

This info is from Robert Lodewyk (sixteengrandsedan#56)...
"The car has rear brake rotors mounted on the front. The offset is slightly different, about 1/16" or more to the inside.
If you put the rears on the front, the rotor surface is closer to that large bolt on the top of the spindle that mounts the
caliper bracket. My #56 had a rear on the front with a spacer between the hub surface and the inside of the rotor."

Robert L. is correct about the different offsets. The dimensions on this car works out fine due to the thickness of the caliper bracket and the use of high strength flat head socket screws.

Robert L., good eye, and thanks for the input!

You're welcome, Robert. That Tom States car looks pretty immaculate.

Thanks Jon. It's a lot of hard work, but I'm enjoying every minute of it!

Thanks Steve and Jon. One more piece of the puzzle solved!

On the former State's A/S 68 Z/28, the front hubs were equipped with these grease caps:



They appear to function as a means to form a continuous conductor between the hub and spindle. I seem to recall some sales hype about static electricity back in the late 60's, early 70's. Maybe I'm on the wrong track here, but what is the point of using these? The car was set up very professionally for a privateer, and even had bearing spacers in the front. For this reason, I'm hesitant to discount their usefulness. Any ideas?
Thanks,
Robert

Sorry to hear of your engine problem.  Hopefully the broken cam shut things down before catastrophic damage  to the block could occur.  Apparently no oil under the tires......that's a good thing!
Keep us updated on the fix.

Eric, your car looks great and a wonderful first outing! I'm anxious to hear how you solved your brake issues.

I ran across some photos of your car before you bought it. You may enjoy seeing them here:

Eric, when you say no power on first brake, are you getting a soft pedal, or do you imply the pads have to warm up before grabbing? If you are getting a soft pedal, you may be experiencing some "pad knock back", likely on the rear axle, but also possible on the front if the wheel bearings are set a bit loose. The quick fix in use is to pump the pedal slightly before use and see if that helps. I have found it to be a rigorous endeavor to set the rear axle end play at a minimal amount as GM specifies. (one good reason for full floater conversions)  If indeed you are experiencing the pad knock back, have your mechanic check the axle end play to see where you are at.
Are you using the 1inch bore master cylinder?

Thanks Jon,  It sounds like most everything else we deal with, OEM is the safe way to go.

Eric, what are your braking symptoms? A couple more questions. Are you running brake cooling ducting? And lastly, power brakes or manual?

A couple photos of a 2-68 cover from a 68Z:
Hope this may help

I don't have personal experience yet with the factory phenolic insulators in the corvette calipers. I have been told from a couple brake specialists that the insulators will not hold up well with the newer extreme compound brake pads. I understand a bullet proof solution are some pricey Titanium pistons that will do the trick.
Jon, do you know what most of the fellows are using in the Historic group?
Thanks,
Robert

Eric, your car is looking terrific. Have you had a chance to do some heavy shake down runs with it yet? What did you end up doing with the oiling system?
Keep up the good work!
Looking forward to some photos of the engine bay and interior.

 I have a couple of knowledgeable paint guys in town, and I would bring the car to them to get their opinion on how to buff and polish the existing paint. You would be surprised how they can use todays products to bring the luster back to old paint.

I wouldn't mind bringing this 68Z home either, but I don't think there is much existing paint to save.
