I have a 1986 GMC 4x4 1/2 ton chassis with a manual 3 speed overdrive (833) transmission, I guess, is what I can find anyway, where would be a good place to find parts for that, front bearing is broke,

If all you need is that bearing, there will be a number on it like 206. Bearings are more or less standardized. Most manufactures use the same numbers. The letters or number after the main number refer to options, like 6206 2RS with two rubber seals:

You must be registered for see images attach

You want a bearing with at least one side open facing the oil. The seals, rubber or steel will pop right out with a small screwdriver.

You'll want to replace the the input shaft seal too, that will also have a number stamped in the metal or moulded in the rubber lip.

Maybe Brewers. They are the Mopar transmission specialist.

That trans would be known as a New Process A833, which is a MOPAR trans with third gear set 1:1 and fourth gear as an overdrive.

Within GM it was RPO MM7 (the merchandised option code) or also MY6 (the non-merchandised option code).
