Refreshing Original Interior Parts

I followed your article concerning restoring original carpet to refresh the carpeting on my 1969 Boss 429. The results were remarkable. Can PPG’s OneChoice SB12 be used on the seats, or do you have any recommendation for refreshing the seat vinyl? Also, what would you recommend for refinishing the fiberboard for the rear package shelf? I am trying to use as much of the original interior as possible. Thanks for all you do for the Mustang hobby!

PPG’s OneChoice Elastomeric Color System works great on seats (vinyl, velour, prepared plastics, etc.) and especially on the Comfort Weave inserts. Be sure to clean the seats well and blow dry with compressed air. I wipe the seats down with lacquer thinner to prep the vinyl prior to the application of the product. Use a minimal amount of SB12 (Jet Black) for best results. The SB12 has outstanding hiding properties, as you found with your carpet. The SB12 will work on your package tray, as well.


Autolite Regulators

I have a 1970 351 Cleveland Mach 1 that was built in September 1969. I need the correct Autolite voltage regulator for my car. Do I need a C8AF or D0AF voltage regulator to be correct? I believe the stamped Autolite ink color is yellow? Is that right? My car does not have air conditioning.

The concours correct Autolite voltage regulator for your September 1969 build would be a C8AF-10316-A with silver-ink Autolite logo stamp. I've provided a picture of the correct unit for your reference.


Boss 429 Coolant Tubes

We have a question concerning the original finish on 1970 Boss 429 heater hose coolant tubes. I ordered a pair of reproductions for my Boss. Both tubes appear to be plated clear zinc or clear cad finishes. My originals, which were damaged and rust pitted on the ends, appear to have two different finishes. The short tube and nut appear to be plated clear zinc or cad. The long tube appears to have no plating and a brass nut. My tubes are not near mint, but I believe they are original finish? What say you? Are the reproductions considered concours correct?

Your observation is correct! The intake coolant tube and nut were cadmium plated. The long tube that attaches to the water pump fitting is bare steel tubing and the nut is natural brass. The reproduction tubes are MCA concours correct in its Trailered Concours Class, but are not concours correct for Unrestored or Thoroughbred classes.
