Rearend modification costs?

Thanks for the replies. Looks like I have a lot more to read. That thread is long. Since I am just beginning the work on the car, I have some time. That being said, I will keep my eyes open for a complete 8 3/4 and talk to a rear end shop
check with a local machine/welding shop as well. Or if there is any race car fabrication shops around, check there too. Sometimes that's cheaper and higher quality than a regular rear end shop.
