In order for this tranny to function you will need to replace both axles. The car will not even move with the 4th gen axles.
Autozone axle part numbers are
Left drivers side 9717 and right side part number is ST1270. Call various autozones as they may say some stup!d sh!t like we dont make them etc..because they are too lazy to check the computer or dont feel like ordering them. The tranny seals are all the same thing from 95-01
left drivers side 38342-81X00 and 38342-81X01 for right side these are the seal part numbers. DAVEB the parts guy was right the internals are different. You will also need to remove your old speed sensor and install it on the 2K-2k1 tranny. If you dont do this you wont know how fast/miles you have traveled.
Hope this helped.
