Purchased 8 3/4 rear I need some help

Is it the jealousy??? Because if some one asked me to work on a 68 Barracuda I would be meticulous and precise.

Last time I had some one work on my car was at Walmart( yes I know what was I thinking) but all they had to do was mount 1 tire. I got it home and decided I was going to swap it for the spare tire. THe freaking stud was stripped to hell. I take it back there to confront them and they told me I did it. OMFG how in the heck do you do that taking the wheel off. So stupid. The wasmart manager knew it was BS and made the guy do to the part store and buy with his money a new stud. it was worth the wait. But lesson learned its better to do it yourself no matter what it is. We will see how the machine shop here in town does prepping my 440 block and crank. Sucks living so far from the city my choices are limited.
