Most parts interchange, some do not. Some parts, if you order new, will automatically updgrade to parts in newer crawlers. 350B is almost the same machine as a 350, but the C has some major differences associated with the wet steering clutches and has a slightly larger engine. Remember also that early 350s differ from later 350s (before the "B" series). Differences between 350s and 350B include the track-frame crossbar, the torsional isolator that drives the reverser, power steering pump, the input shaft and drum in the reverser, the reverser pump, etc. Also, the transmission case, steering clutch housings, and side-frames were beefed up along the way, but they are interchangable. The reverser, when in forward, is direct-drive - no gears are working. When in reverse, all power is transmitted through a countershaft that is driven by some very noisy straight-cut spur gears that whine and also the input shaft is counter-rotating against the output shaft via a dinky little bearing that often fails in early 350s and 1010s. Later 350s, 350Bs, etc. use a larger center bearing.
