I have two used gear sets from my Cutlass that I will not be using anymore so figured I would pass them on.

The first set is a OE 3.73 (11:41) from our old 86 442. The car had a bit over 100K miles on it in stock condition and then had about 5K miles put on it with 300whp. The gears never made any noise and are in good shape, bearings were fine when they were removed. Asking $75 shipped for this set

The second set is an AAM OE replacement set purchased new from DTS a few years back. This is a 4.10 ratio set (10:41) and I used this set about 6K miles behind a stock S2 3800 that I had in my 86 Cutlass for a few years. These gears replaced the above set of 3.73s, then I switch down to 3.23s since the car is now boosted and doesnt need the gear. This gear set is in great condition and I am asking $100 shipped

PS- On a side note, I am open to suggestions on how to edit your original starting post to a new thread! I already made another post earlier in the for sale section and would have added this stuff to that post but cannot figure out how to edit the main title and original post on this forum. I know there is a 2 post per day limit and by that I am safe but I do understand the clutter and have no problem using an existing thread if it can be modified to add more stuff.
