I have a 4" lift on my 85 shortbed K10 with a 12-bolt rear end and 10 bolt front. I have don't have the T-Case dropped because of my exhaust, it causes it to not line up properly (have headers with full dual exhaust). It seems like my rear driveshaft is shorter than I prefer, seems like a lot of the slip yoke is sticking out the back of the T-Case, so i'm thinking about getting a one peice shaft out of a longbed and having it cut-down to the length I want for my lift. Or I could have my stock driveshaft lengthened, but I think the shortening method would work the best and be cheaper. Does anyone know about what it would cost for this to be done? And I realize that I won't get an exact price, just looking for a ball-park.
