I have been busy the last couple days, but I am still going on my conversion. The old, flattened trans mount slips in fine (even though the top holes are wider on the long tail TH400's). So I got a new trans mount. It is too tall. The stock crossmember will work fine, if I can get a slightly shorter trans mount. Does anyone have any good leads on a sort of, low profile trans mount for a TH400? Thanx.
