Weights?? Depends if it needed balanced. I don't have the p/n but if it is a LSi 3" dia aluminum dr shaft there is only one the other is steel. Also it will fit any 3rd gen except some V6 cars.

If its used then it should already be balanced.

one way to find out is to put it in and c how it feels. Its not hard to swap a driveshaft it takes what 10 to 15 min and 4 bolts

If a weight is missing, you'll see where it was located on the d/s. My experience with JG1 shafts was that there was always one or two weights. Though I had 60+ of these in my possession at one time or another, I only remember a couple that had missing weights. If I were guessing (and I am), I'd say you were good to go.

they are too short for the early 200c and the 4 speeds. the t-5 and the 700r4 they will fit. v6 or v8 doesn't matter.





you use a torch to melt the plastic like you do the steel ones.

I have a 1990 IROC-Z with the 5.7 motor, 700r tran. and the 9 bolt borgwarner rear end. I have a aluminum drive shaft with a three rivers sticker on it with a part #12564004 will it fit my car?
