Correct Blackout and More Vintage Mustang Concours Technical Questions Answered
I have a 1971 Mustang Boss 351 in Competition Yellow. I was recently told by a MCA judge the back edge of the hood underside should be blacked out by the cowl? I have not seen this detail. Did all Boss Mustangs have this area blacked out?
The black out on the underside of the hood was typical for the 1971 Boss Mustang. The rear edge of the fender lip was also typically blacked out. I will include a picture of both features here for your reference.
Dying Vinyl and Plastic Parts
What is the best system, method, and product to dye an original green 1970 Mustang steering wheel pad to black? How durable will it be once dyed? Thanks!
The product I use is PPG OneChoice SB12 Jet Black. Correct prep is very important here for something like a steering wheel pad where your hands/fingers will often touch it. Clean the pad extremely well, then wipe the vinyl with lacquer thinner. The thinner will soften the vinyl slightly and actually help with product adhesion. If dyeing plastic the lacquer thinner may melt the plastic, so be careful and test an inconspicuous area first. A red or gray Scotch-Brite pad works well on plastic parts too.
I need info on what should be the correct Boss 351-specific alternator and pulley for said alternator. The pulley appears to be a tough find from my research. Could you provide the casting numbers on both items for me? Thanks much!
The correct engineering number for the alternator is D1ZF-14300-AA. The Ford part number for the pulley is D1ZZ-10341-A. The number stamped in the pulley is D1ZF-10A352-A1A. The pulley is indeed a rare find. Jack Brooks at Dead Nuts On has outstanding Autolite alternators, pulleys, and mounting hardware. You can reach him at (510) 903-1059 or deadnutson.com.
