what are my options for tcases behind a c-6. currently it is hooked up to a 208 with a fixed front yoke. Have chev dana 60 front but no way to swap to transfer case with passenger side drop short of making my own adapter. never worked much with ford always used chev in past. can i use a jeep 300 or 20 or achev tcase somehow help

neither the 300 or D20 will work w/o an adapter....Any other fullsize ford T-case will bolt up though.

NP203, NP205 and BW1356 have 31 spline input shaft and 6 bolt round bolt pattern

If you are into so mods you can replace the input from a Chevy 205 with the ford set-up, then you have to redrill and tap the holes for the Ford setup.
