I could tell you.......but then..... ::025::
I forget. (I just dug the stuff out.)
I had everything "bolted together" then, used a sharpie to mark where the nut plates were (rough). Once I took it apart, no prob. Centered the tabs, drilled tiny holes and popped them in. I could only find the nut plates in NOT metric, so, new bolts. Uses the same AltRider Washer things. I hogged out the left front brace to the "larger nut plates". (I should have hunted for smaller ones, nah, project got done.)
