yah i had a screw or 2 on mine that wasnt too good upon reassembly or disassembly the heads strips out, so yah, thats a valid point, but i also can go down to local ace hardware store and buy new ones cheap, so really not a issue. i have heard the thing bout the diffs being a lil different but on mine mine had the alloy diff, BUT it had NO fluid in it, so a first thing to do is pop it and fill it, if it has the plastic case i reccommend getting the alloy version, and the plastic diff outer case was plastic on mine too, i sprung for the split diff case so now my whole inner and outer diff is metal, one other thing i highly reccommend too is get a set of fast eddy bearings and as you tear down swap out the bearings with FE ones, and remember to add the missing one inside diff housing that sometimes isnt there. mine was there, but i swapped it out anyways, the brakes, yeah not the best deal there, i swapped mine out for a TR one piece upper mount setup, miner drilling of a upper plate hole to fit the recessed end on one TR post, but again no biggie. mine has the 2 speed gearing, now the clutch, well, isnt too bad as is, but i upgraded to a alloy version of the stocker 3 point arm style, with oversized FE bearings. tried the enclosed one, not happy with it really, so stuck with ally 3 point setup instead. the first major thing that ever happened right out of box was the PS it screwed up on 2nd tank, replaced it with a collared pawl version no probs since.
