89 240SX/S14 DIFF PROBLEMS. PLEASE HELP

[BRADYNS240SX]

I am going crazy, I cant get the short shaft all the way in the pumpkin with the new diff installed. Also I have got to get some shims but unsure where to get the correct shims to fix the pinion gear back lash..There is too much play....Anyone ever actually done this?Let me explain in a little more detail what I have going on. I have an 89 240sx with 6 bolt half shafts. I purchased a S14 VLSD off of e-bay that came as the diff and the 6 bolt half shafts. NO PUMPKIN.So what I had to do is take my Diff out of my car, pull the cover off,take the half shafts out, remove the ring gear from my original pumpkin, install it on new pumpkin. Then reasemble the diff, Took my new 6 bolt shafts that came with the new diff. and install. got the longer shaft in no problem the shorter shaft stops about 1/4 inch short. Will not go all the way in like originals did. What is up with that? Also need the shims for the ring gear. Seems to be way too much play...

Any help would be great. I may have to end up taking my diff to a nissan mechanic to get this right.

try beating the thing in? take the diff front cover off and see what the shaft is hitting before you try beating it in.. .. make sure it's lined up and there is no garbage in the way.. g/l.

I had the cover off. I actually had to put the s14 vlsd into my s13 pumpkin because the one I bought came as the vlsd only no pumpkin, I have beat and beat on that thing it will not go all the way in.
