How ironic,
I just installed a Summit gear reduction Mini starter on the 302 in FIA #39. I went with their part SUM-820055. It cost $149 plus $11.75 "handling charge" but shipping was free.
I was able to eliminate the firewall solenoid and the only piece I had to make is a new (longer) #55 wire down to the new starter.
I did have to rotate the mounting plate by one hole for block clearance (there are about a billion different holes available) and you have to put the top bolt in place before you put the mounting plate back on the starter motor.
I have the original 1999 battery mounted in the right fender and other than an annual cleaning, I've never had a problem.
It sounds great, spins the motor fast and I am a happy camper.
