my old alternator in my new car?

[loudenuff]

I used to have a 99 Grand Prix 3.8 in which I installed a 275a singer alternator in.. I just sold that car but I took the entire elec out and put the stock one back in. so now I'm wondering if I can install that alternator into my new 06 Buick lacrosse cx 3.8? I know I'll need the 4-2 pin converter wire but will the casing fit? I'd rather ask incase anyone knows than go through the trouble of taking it out. any answers are greatly appreciated

Go to autozone and buy your stock alternator and compare them. Then return it

Even if it doesn't fit you can always send it back to singer to get re-cased.

Not the cheapest solution, but you have to see if the vehicle is regulated by a regulator or pcm or both.
