shimming my gp4 diff in the plastic housing but can't seem to get a good mesh can't fit anymore shims in anybody else have this trouble
 
Shim behind the input to push it closer to the ring gear, the goal is not to have any axial play with the diff assembly left to right. Shim the input until it binds and then remove the thinnest shim, ensure it is smooth throughout the entire rotation. Plastic cups and bulkheads will eventually become oblong from thermal expansion/contraction.

These will shim your wheel hex tight as well:
