When you get the adapter, it will come with an output shaft to be installed into your Tranny. Is the tranny a 700R4 or 4l60 cause that was the transition year. Is there 6 bolts holding the tailhousing or 4 bolts ? If there are 6 you might need an extra adapter plate, check with AA. Also when looking for the AA adapter, check other distributors, cause they might be cheaper. I got my AA adapter from Inchworm for 100 less then AA, and it was drop shipped from AA.
