I have a MWC rear with body mount torque arm. I dont have the stock bolts what size and pitch and length are they?

I honestly dont know the pitch and length. But when I put mine up, I realized I didnt have any hardware for it either, so I "borrowed" the bolts from my bump stops over the rear end. lol. They worked perfect. You can take one of the bump stop bolts out and measure it. Hope this helps.

 

Direct from them M8x1.25-20mm long use washer and locks

 

Like he said ^^. I got mine from Home Depot.
