A question for the masses. I have an AC engined Aceca that I would like to fit with an overdrive gearbox. My car came with the Moss box and I have given consideration to obtaining one with overdrive and fitting to my car with the necessary modifications. An issue I have with this is the problem with worn syncros typical in the Moss box and the inability to replace them. Being aware that AC offered a "lightweight" gearbox that has been described as TR gears in AC's own casting I am wondering if anyone has attempted to use a TR overdrive gearbox. The only picture I have seen of one is the cutaway in the owners handbook that looks to me very much like a TR box with the bell housing machined off and a different one bolted on. Has anyone explored doing this using the AC / Moss bellhousing and a modified TR gearbox (I realize that the input shaft would need to be machined for a female pilot bearing, amongst other modifications). I am beginning to prefer this option given better parts availability for the Triumph box as well as the remote gear shift position, etc. I am not interested in any modern 5 speed conversions so I really have these two options. Your experiences would be appreciated!
