If you could find the brackets from a small block ( I am assuming that's a poly V8 but you didn't say) LA police cruiser with a 100 amp alternator it might get you close. I'm sure some of the M body police cars had them.
yes, that is my problem. there is an alternator on eBay but I have no way to adjust it. I wish there was a car type alternator that would work but the voltage regulator says 14 volts. there is nothing electrical on the truck other than a spot light that would require more juice and ive been told by a few people that the alternator is only a 60 amp unit. The Leece Neville voltage regulator says its rated for 40-65 amps. I'm probably going to find a standard engine harness and put electronic ignition in it until I can find all the Leece Neville stuff.
And yes, it is a poly motor.
Thanks for the help guys. If any of you have any tips on getting a charging system working with what I have, let me know.
