get the installation kit because there are additional parts that they need to install the gears: u know bearings, seals, and other fun stuff. They will just use the old stuff if u do not bring them the kit, that is what a lot of places do. But for sure u get richmond gears they are really strong, but they howl alot, only draw back to driving with them on the street but u get use to them. i paid 250.00 for install. I have 3:73 and they pull real good, just to give u an example i saw at the track. I ran a few hatches at the track, talked to one guy with 87 just like mine, he had the stock 2:73 and his best time was a 15.5 he had headers and o/r h-pipe and slicks. I had 3:73's off road h-pipe stock headers and street tires and ran the best time of 14.2 @ 98 but what do i know the kid maybe couldnt shift
