For those of you who have swapped in different gearsets, which manufacturer did you go with and how did the swap turn out? I NEED to get some 4.88's in my 62 but I don't want to spend all that mula just to have it whine down the road. I've heard Yukon and Precision make good gearsets, but I want to hear it from you guys!! Which manufacturer should I get my 4.88's from???
