Thanks for the link ddgonzal!
I'm hoping that someone has a set of (8) of these NISMO 40222-H5020 2" wheel studs (for drum brakes) collecting dust on a shelf - they already have the relief ground in the circular base to lock them in place on the axle (like the stock units) and the 2" includes the tapered "dog" or blank area before the threads begin to help alleviate cross threading the wheel nut in the heat of battle. Aftermarket choices will require machining the axles & studs to fit and I've already got the NISMO front studs in place.
Besides, they look doggone cool, very 70s TransAm.

The stock wheel studs are 38mm long.

Yours Truly needs a set of (8) PN 40222-H5020 racing wheel studs for the rear axles in my ongoing 1200 racer resto. These studs are NLA from NISMO. Trouble is, the front hubs already have NISMO studs, but the aft end has stock studs, and tech inspection won't take kindly to that. (they're a bit too short for their liking) Also, the 1200 studs are 1.25 thread, while metric aftermarket are 1.50 thread. Can anyone help me out? Thanks!
