It's a special shanked bolt to match the driveshaft flange. Buy them from Mazda.

Damnit, I just ordered a bunch of crap from Mazda, didn't think to look for these. Subscribed.

I've been using Grade 8 3/8? coarse bolts since I went with my torsen swap...so for ~70k boosted miles and 10 years or so. The 4 bolts don't locate the driveshaft.

The bolts aren't critical since that tit actually locates the drive shaft. Any bolt capable of supplying the required clamping force should suffice. IE the same size in grade 8 or grade 10.8.

Using non factory bolts in SCCA stock, ST, or SP would be protest-able. But the result would be the protester getting punched in the dick and you being penalized 0.001 seconds or less.

Even with this info it's surprisingly difficult to find the actual dimensions.
The dealer can't even pull the spec. They want 50 dollars for all the parts which is F'n rediculous as rosenthal only wants like 11 for everything. I'm thinking about buying the bolts and sourcing my own washer and nut.

Edit 2: Picked up 4 M10-1.50 x 30mm grade 10.9 flanged bolts with no shoulder. I'm going to put some thread locker on it. I'll report back in a few weeks to see how they hold up. If you are already ordering from Rosenthal you might as well buy the set: DRIVESHAFT BOLT SET (PKMIAD1104) - $10.95 - PKMIAD1104 . I'm impatient.

Edit 3: flanges too big. **** it I'm buying the stupid set for 50 dollars to my door. Not worth the time.
