Not to derail your truck thread on OD transmission's but years ago there was a gearset available for muncie 4spd's that would effectively make 3rd OD and then you flipped the shift lever so 4th became your new 3rd, so on the shifter you would still do the normal 1-2-3-4 but it would actually be like 1-2-4-OD. I think you used it with a close ratio trans so the jump between 2nd and 4th wasn't too big of a gap, can't remember though.

With all the new technology I wonder how hard it would be to get a set machined or rough cast then machined correctly.
