Another "Yard Scrambler" update.
Took the transmission apart, everything is in great shape. No busted or chipped teeth or damage to any shafts. I believe the 80,000 mile reading on the odometer is correct.
All the transmission small parts. No damage here, not even any wear to the original thrust washers or snap rings.
After cleaning and inspecting all the parts, began the reassembly. Used a rebuild kit, so I changed all the roller bearings and the two big ball bearings and snap rings. I reused the factory brass thrust washers because there was no wear on them and I like them better then the rebuild kit supplied plastic washers. Picture of the reverse gear assembly and cluster shaft installed.
Next up was the main shaft. I installed new synchronizers blocking rings, the shiney brass parts. Main shaft goes back together fairly easy, just make sure you put all the snap rings on, don't forget the thrust washer, and install the syncro hubs on facing the right way.
WORD OF CAUTION ON THE SYNCRO ASSEMBLIES - There are two different size little metal tabs that go in the syncro assemblies, 3 short and 3 long. The long ones go to the 1-2 syncro, the short ones go to the 3-4 syncro. The FSM does not mention this, so be careful. I assembled this transmission, went back and looked at one of my parts pictures, and realized there are two different length tabs. Had to disassemble the transmission and reassemble correctly. I don't think I caught this issue when I put the transmission back together in my red Scrambler, and after driving several thousand miles I have not had any issues. It might not cause a problem, but BE CAREFUL.
Main shaft, input shaft, and rear adapter housing installed.
The reassembled shift tower assembly.
Only issue I had with this transmission - One of the threaded holes in the front of transmission case that secures the front bearing retainer was stripped out. I re tapped this hole and used a slightly longer bolt to secure the retainer, after making sure the slightly longer bolt would not rub against any moving parts in the transmission. Be careful threading steel bolts into aluminum housings.
And the reassembled transmission.
That's it for now.

My red Scrambler had "bouncing speedometer needle syndrome" due to being wore out
