Hey Guys, I came across a '75 J20 w/401 motor and I'm constantly having ignition problems. At first it was the ignition module (small gold box on passenger side fender) replace it, started just fine, 2 weeks later, the coil, then back to the module by end of the month. Looking to upgrade components or complete system. Budget around $350. Vehicle has Prestolite distributor. Any comments are most welcome.
