Rearend modification costs?

8 3/4 B body with the right wheel offset no modifications if it is early B body like a 67. When you talk cost are you talking labor. An 8.8 will cost you total from 200.00 for complete with discs and figure another 150.00 to 400 for a drive shaft. The drive shaft you will have to do regardless of which rear you are gonna do. There is an 8.8 Seap thread on this site that has all the info.
