The only reason I brought up the pucks is because the "hat" thrust washer from the pucks rebuild kit was no specifically designed to be run with the caged. I also tried to just use the caged thrust washer and no MIP hat, and it seemed "fine". I just didnt like the lack of support for the screw. Matt from MIP said the complete caged thrust "should" be fine. Again, the mip hat thrust is the part of the build I am unsure of
