I put a 6 inch lift on my 78 chevrolet and after i got everything on, the front drive shaft wouldnt go down far enough, so i dropped the t-case about an inch... so after doing so.. all it wants to do is grind when i put it in drive or reverse... something to do with the linkage because it worked before i dropped it but i have to drop it to fit the front d-shaft..

Any ideas welcome
