So I need and Alternator for my 1990.. I figured since it was a CS-144 case ( or so I thought) I could get the 140A one from an LT4. Well, it will not fit..

Ah well so much for trying to out think GM. LOL

Got the correct Alt on the way.

One thing I found interested was the old alt. will nto even spin freely, man that thing was pretty much toast..

Jeff,it will fit you just have to grind a little here a little there to get it to fit.

Jeff,

You're fortunate it didn't lockup like karterdon's did in BG a couple of years ago.
