6\" Lift - Th350 - NP203 - 14BFF Driveshaft length? I'm running around in 'Front Wheel Drive' while I get a new driveshaft made for the beast. I'm a bit ahead of myself with the driveshaft as the 14bFF is still in the garage. Rather than getting a temporary fix, I'm planning to get the driveshaft done right and get this axle in. So, the question... I have a 1978 k5, 6" Lift - Th350 - NP203 - 14BFF. I'm looking to get as much flex out of the rear end as possible which will translate into a lot of driveshaft compression. I would truly appreciate any driveshaft measurements of anyone running a similar setup at fully compressed and fully extended positions so I can get this gear in and running, without having to temp it for too long. I think I'm going with a CV style but with either measurements, I can get the rest worked out. Oh, my axle housing center of the axle to center of the yolk u-joint is 14". Second, I'm getting quoted around $500 to get a larger diameter u-joint t-case yolk, a new heavy duty CV-joint shaft with spicers on both ends... any good?.. or should I keep looking?
