Originality / original wheel paint
« on: December 13, 2010, 04:05:01 PM »
I'm curious if in '69 the body colored wheels were painted in lacquer like the cars or if they were painted in enamel.  During the assembly process were groups of wheels painted and then just picked when the tires were mounted or were they shot at same time as the sheet metal?

Originality / brake caliper castings
« on: March 23, 2008, 12:47:32 AM »
My friend was redoing brakes on a C3 Corvette and found when rebuilding calipers with O ring pistons yhat one caliper had smaller piston bores.  Corvette supplier told him they were probably from a Camaro with rear disc brakes because of bore.  Casting #'s are 5473807 and 5473806 on split caliper.  Also has a 2 and 6 on caliper.  Anybody know what this fits or if it is Camaro?

Maintenance / Brake caliper help and questions

 I have a problem with my '69 front calipers. First I had problem with car pulling to right so I changed the brake hoses, (few miles but 12 yrs old with silicone fluid) still pulled a bit but after dragging brakes for about 1/2 mi it cleared up and was fine however had a leak between caliper and brake hose fitting. I cannot get the leak stopped. I checked caliper for cracks, none, and hose appears OK. Seating surface on caliper looks OK but didn't get good crush marks on copper washer but it was correctly torqued then slightly over torqued and still leaked. New washers were about .003 thinner. This leak was static. I removed caliper inspected everything again and bench tested with air but still get leak. I'm ready to pull my hair out. Anyway, I'm just about ready to replace the calipers although I hate to give up these as I'm 99% sure they're original and had them resleeved with stainless by Stainless Steel Brakes 12 or so years ago. I looked at the catalogs and I see "technically correct" so I assume same caliper used for other years. Anyone know what is correct casting #'s for '69 and how many years they were used? One catalog lists cars made before and after 11/69. I can't find any info on numbers anywhere...books or on the net. Anybody know what we need to look for? Any rebuilt calipers better than others? What is the correct finish on ' paint or natural? What are the restorers using? Thanks

Maintenance / brake problem

I've got a problem with my '69 brakes pulling to the passenger side. I thought it was the left caliper piston sticking but when I pulled the caliper and compressed,the piston then stepped on the brake pedal to push it out. Worked it in and out a few times this way and put back together but the car still pulls to the right when brakes are applied. Rotor rotates easier on left side than on the right after brakes are applied and released. Could left caliper be bad? The car is a trailer queen and gets driven very little. All parts were brand new when restored 10 years ago. Calipers were rebuilt and sleeved with stainless and have always used silicone fluid. Thanks

Restoration / Undercoating in wheelwells

Is there a product that duplicates the undercoating the factory applied to the wheelwells?
