Default torquing pinion nut

I'm in the process of putting my changing my rear end to 3.6 gears. I'm at the point of torquing the pinion nut and setting the preload. Trouble is the pinion spins while attempting to get the proper torque.

Question is, what do ya'll use to hold the pinion from spinning while torquing that nut?

I would assume the parking brake would do it. No idea with it out of the car though.

Unsurprisingly, the manual suggests the use of a special service tool to hold the flange while torquing:



You could easily make something equivalent with some steel bar stock. Same idea as a crankshaft locking tool for installing the center crank bolt.

Use a pair of C-clamps and some blocks of wood to clamp the diff to your workbench. If you have a workbench you don't mind drilling into, use lag screws instead of clamps.

Do you have new shims for your swap? I'm doing the swap as well and need new shims. Where did you get yours if you did?

I see. My college is doing the work and the instructor said I need them (they haven't torn it apart yet) and my Mazda dealer no longer sells them. And no one else sells them. Every kit I found excludes shims...

Do you have any leftover parts? Mine had a lot of extra leftover parts when I was done. Same with my dishwasher.
