i tried looking for info on your rig, but this massive 77 page thread is kinda ridiculous LOL, (in a good way)
who built the rear case? how old is the bearing next to the broken teeth on the counter shaft? is it a new or used bearing?
is/are/were the #1 and #2 housings paired from the factory? what condition is the main bearing in? for that matter, how do all the bearings look? did you replace them all after the first set of gears went bad?
also, what engine you running? hp? trans? tire size?
when i first saw these pics, i thought it was a bit odd...
also, what number gear set are these?
