I want to convert my 87 TPI to a serp belt set-up. I was just gonna buy the stuff off of someone. Is there a certain year or something I should be looking for, or will any year serp setup work?

 

The 3rd gen F-body serp setup is the same from 88-92. Very easy to do. You will also need a serp crank pulley and a new water pump as the serpentine pump spin's counterclockwise.

 

There's some place in florida that used to sell conversion kits. I paid around $150 for it a four or five years ago. It just includes all of the accessories and the brackets, pulleys. I don't know if it's still in business because I can't find the website, but maybe you can. AFAIK any year should work, even some different car models would work.
