does anyone know if theres a quality, off the shelf, premade wireset for these cars with 90 degree boots? im running gt40p's with bbk shorties, and a normal 135 wont work on #6&7. ive tried the cheapo autozone specials for a chevy van with a 305, which has the right ends, but its a sloppy mess on a 302, and way too easy to burn up. is the only alternative a universal/cut to length set?
