Hey all, I have an 86' Samurai with a few mods, I want to add a GM alternator. My buddy gave me a Trail Tough bracket and said I need a Delco 12 alternator, I have been to a few local shops and no one knows what I am talking about??? What are you using? Any help would be appreciated.

Do a search for GM Alternator, should find everything you need.

d1ose12          or 7-69035-20436  or an 1985 suburban with a 454 and all the accessories.  100 amp.

Thanks for the replies, did a search and still cant figure out if I can use the same belt and pulley?

use alt pully from gm alternator (1985 suburban has v belt same as samurai) and different belt.

i know when im doing mine im going with an alt for a 1996 silverado 1500 heavy (trailer package) with the 350 v8 (has the 130amp! (coworkers truck specs...))

I managed to find a 15 SI and shoehorned it into my Samurai...

The best way to select an alternator (10/12/15 SI) is to go to the junkyard and grab one that has the same belt pulley as your truck has.  Get it tested and "clocked" at an alternator shop so that the electric wires will be easy to access for service.  If you picked up an alternator at the junkyard and it does not work, use it as a core for the purchase of a new one.

Since you have the bracket, you have the big part of the project behind you!

Good luck!

Thanks again for the replies and the Link ACK! This clarifies the whole process.
