Looking for rear axle carrier pinch bolts for TRX90

Howdy all! I am a teacher in SW Missouri and have a small engine repair class. I have a student who is working on a TRX90 (2005) that someone has welded the rear axle to the carrier… effectively making it solid and non-adjustable. Well, we cut the weld and are attempting to put it back together the correct way. BUT, all of the schematics that I look at don’t show the bottom 2 pinch bolts that hold the axle to the grooved holes on the carrier. The left bolt also keeps the tensioner in place. Could someone find out what size that bolt is, or post a schematic that shows it?
We are missing the bottom 2 pinch bolts and need to know what size to order or find.

Thank you!
