I pulled the alt. from my 83L parts car, and it is totally different from my 82P one. The belt is one big wide 7-groove one, as is the crank pulley. The 82 is 2 v-belts. Can I switch these over, pullies and all? I read that you have to jumper some connection with a resistor to run mk4 alt's, but I cant seem to find that post. Also, if I score a mk4 alt. will it work with these pullies?
