drive shaft trouble
 

I put a 4" lift in my 71 blazer. The drive shaft is about an 1 1/2" short fully extended. I do not have the body on the frame now. Will the drive shaft work once I put the body back on or do i need to get a longer driveshaft, is it going to go down that much? is it normal to have a driveshaft problem with a 4" lift kit (rough country)?

I would not do anything until the frame gets weighted, to let things settle and get an accurate measurement. I would not even fully tighten things down until it has all it's weight on the suspension.

If the shocks fit right now, the shaft is too short. You have the possibility of hitting a bump, and dropping the shaft. I agree, dont worry about final measurement until it's fully loaded.
