I have a cs130 off a 87 buick GN on my car.You will have to mod the spacer to the head and the adjuster bar will need to be ground to clear the alts fan on a big block. The resister has to be there or it wont charge, and some alts you will have to experiment with the resister ( 50 - 100 )ohms and if I remember correct 1 watt. Radio shack has them and you just solider them on the wire. I just have the s wire jumped to the big batt stud on the alt and the l term is the 12 volt ignition with the resister. When looking for cs130s you need to find the ones that have the mounting locations 180 apart. Also you will need a v belt pulley off a older gm alt as the buick and most of the cs130s come with a serp belt pulley.
