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?

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.

I've recieve a tool for tightening the locknut. Torqued it till the preload was 10 in lb. Ended up being 190 ft lbs. Removed the nut and flange. Installed the oil seal and reinstalled everything to the 190 fl lbs. Now the pinion wont spin by hand. Even at the lowest torque for the pinion nut (97 ft lbs) it take 40 in lbs to turn the pinion.

You get the shims from mazdamotorsports. You won't know what size you need until you get it apart. There's a whole bunch of different bearings and parts you should get when you're doing it. A call with MMS is very helpful, the guys there are super nice. I swapped my own gears and I wish I hadn't, it's a much more specialized and involved job than most realize, including me at the time.
My recommendation is taking it to a shop to finish the job.
