Those are all pretty cool.
I don't have pictures handy, but I modified a parts store 3 jaw puller to be comically long for pulling 5th/6th gear in T56 Magnums. The Magnum/6060 countershaft is 1 piece, not two, so you need silly long pullers to pull the rear gears. I just used some 1.5"x1/8" steel bars and extended the jaws. Worked awesome.
I also have a drawer of cut, bent, and welded wrenches, most of which are for tightening turbo stuff. narrowed and shortened 1" open end wrenches for tightening 10AN drain fittings between the housings with zero room, or front T4 bolt/nut on rotary engines where everthing's jammed against the block.
