Also I wouldn't mount the transfer case until You have the engine and

             tranny in place because the angles are critical if you want to keep

             vibration to a minimum. Also when you get this thing running, the

              "phasing" of the center shaft(between the trans and t.c.) will

               affect the vibration factor. You want all the joints to be "in Line".

               You can change this by putting the t.c. in neutral(engine idle),

               and put the trans in any gear and letting the clutch out a little

               to allow it to turn "a little". Normally, this will correct itself.

                      I did mini-truck 4wd conversions, back in the 70's, and

                we had to deal with this on a regular basis.

                                       Hope this  helps
