I just installed new BDS 6" lift coil springs on my 75 f100, along with the BDS radius arm drop brackets. Now every where I've read about lifting these trucks is that the front driveshaft will need to be lengthened, which mine will need, and to use 7* C-bushings. Well I got those bushings, but when I went to install them, the bushings that were already on there appeared to read at 8* so I left them on. After installation of everything was done, here is my front driveshaft at the T-case:



It will not turn all the way around. Now my question is, how will 7* bushings work, if 8* don't? Or maybe the 8 was actually a 3? I need help to fix this or I won't have a clue about what to do.
