I've searched about it and found a couple threads but I am still confused. Can somebody explain to me what all is required for a GM 1 Wire Alternator swap on my '88 22RE. the alternator I already got is a ProForm 100 amp part# 664451N.

 

I believe LCE has brackets/install kits for this set up. check them out. there are others out there as well that have the kits. this will give you a good idea in what you need. Below is the direct link to the section.
