I'm sure that the manual trans diesel will have a quite a different flywheel, and maybe clutch, from gas burner motors, but I imagine that one could be obtained from Yurrup, and pilot bearing differences can usually be dealt with by a little machining or a shim/collar on the trans input shaft, but I'm not 100% negative about automatics anyway -- I was only curious as to whether a manual trans alternative might exist in the USA at all.
