a while ago i got a posi for my car, realised the axle was bad, but didn't have anythign to replace it with, so i just put it back in "temporarly". about 6 months after i got a new axle i decided i might want to get it in. i go to autozone, car quest, advanced, all thoes places looking for some axle studs, no one has them. fineally i decide to bite the bullet and go to napa, they have everything, at double the price. i ended up getting a set of studs for a 7.5" rear end, even though i specifically asked the guy to make sure he entered the right engine in the computer, but he insisted he had it right, he said that the computer said they all use the same bolts. today i head over there to take them back, and theres no line, the one thing i love about napa. i tell the new guy i have the wrong bolts, and bring my axle in with me to make sure the new ones fit. so i ask him to do a search for a regal with the turbo engine (why don't they have the gn on the list), he gets the part number and comes back with the exact studs i tryed to return. he then went on to tell me that the axle i had wasn't out of a regal, or "this grand national car your talking about". I am no parts expert, and i don't know what else used an 8.5" rear end, so i ask him to do a search on a 1/2 ton truck and a z28 camero, figuring one of thoes 2 should have the same rear end( i thought they might anyways). about this time the guy who sold me the first bolts comes out and askes me whats wrong with them (nice guy) and tryes to help, then goes and looks in some boks trying to find the right bolts for me. the new guy comes back with 2 boxes of bolts, neither fit. then i think he said, "you obviously don't know what kind of car this came out of, so i can't help you" its times like this i wais i had a mustang, everyone knows about them.... then he askes me what its for again (by this time i'm not very happy, but i see a lot of humor in it that this guy doesnt' get that his computer doesnt' have all the answers) the manager who helped me the first time came over, measured the hole, and found the right bolts for me, as hes going that this other guy tells him that i drilled the holes out, so after about 20 minutes i fineally get the right bolts, and this new guy and the manager arguing. just sharing my day with all of you.
