These are a set of four, upper control arm adjuster mounting bolts and washers, that are used on the following Mopar automobiles. 1970 - 1974 Barracuda & Challenger, E Body cars. 1962 - 1972 Charger, Super Bee, Roadrunner, GTX, Satellite, Belvedere, Coronet, all the B body line of cars. 1962- 1976 Duster, Dart, Demon, Valiant, Scamp, Swinger, all the A Body line of cars. Excellent factory parts for all you guys living in the rust bucket states, when your replacing the bushings in your upper control arms. I found another box full of these parts, out in the garage, from my rebuilding days of suspension parts, for 4 more cars. $35.00 for the parts, + $9.00 for the mailman, (In the USA), + Pay Pal. Send me a pm, and i can then send you my payment e mail address. Thank's a lot.
