Driveshaft Extension?

[TB2Blazer]

I have an 85 K5 blazer with a six inch lift and I am about to go have my rear driveshaft extended. I was just wondering if anyone knows how much I should extend it 3 inches 4 inches? Any help would be most appreciated.

i doubt it needs that much....i only had to extend mine about 1.5" for a 7" lift with 1" t-case lowering. theres an easy way to measure. go to www.drivelinesolutions.com and it tells you how
