That looks like a HD offroad unit. It isn't a COPO 234 unit. Those gears appear to be the 17 tooth axle gears and the springs/plates are either 400 or 800 pound preload parts. It also appears to have the notched pin for 5.13+ gears. Hope this helps.

Eric, I will have to ask my friend Mike his shop did it I told him it was a heavy duty unit and rebuild it as that I will see if he has the stuff that came out of it, he throws nothing away, the other side of the housing is different than I have seen just a small hole

Eric, Talked to Mike he said he replaced everything in the case, but it was exact what came out but the cross shaft was notched said it wouldnt be a problem? Also it has a L or E 27 0 is this a date code? if so it fits close to the 4:88 gears could be it was all changed at the same time if so. Also it has a BT stamp on it no clue there????
