more stupid ideas. but im getting better i swear... ive been thinking hard about whether fitting a 55 box into my stepdown will work and its all pretty useless thinking without any basis for comparison, so i had to do some measuring.

after visiting steve conyers this morning and measuring everything id have to change i finally decided its just too much hassle. the bellhousing is a lot longer on a 55 and would put the trans mount too far back to make it a simple swap. im a heavy fabricator by trade and converting stuff is what i do for a living but even im not touching a crossmember relocation in a stepdown. while the larger input shaft and simpler clutch are good ideas its a big hassle making it work.

which brings me to the next problem. there is one twin lever od trans in all of oz thats not bolted down, its in steves shed and its not in a good way. i have a good 55 od.

The big question is- how much of the 55 guts would fit in the 54 box. input shaft would have to change. or where could i get a GOOD 54 OD box. if all else fails i will just use a standard 3 speed and play with my final drive ratios until i'm happy.

    You should be able use everything except the input and output shafts, but hardly worth the effort. The term "Hash" adequately describes the '55's, as things were hashed around to make the Hudson parts work in the Nash frame.

    im convinced that it should work, steve is a bit more hesitant. the main case casting is the same item. internally all BW OD units are the same. the casting for the OD is different so the torque tube housing can bolt up, but has the same basic shape aside from that. i cant see how things would be any different.

    since the 54 box would have to come apart for a rebuild, i may as well do that and put the 55 internals in. meanwhile i'll just think too hard about it.

    Hudson and Nash used the same basic transmission , the T-86 Warner but with differences in the input shaft( spline and length) and output shaft( length and Nash used torque tube drive. If the internal parts would fit or not would depend on the ratios for first, second, and reverse .

    i asked steve to check the tooth counts to make sure that the ratios check out. hashes were a rush job so hopefully gear ratios were the last thing on their minds

    ok so im going to settle for a standard 3 speed. no big deal.

    bob- i will get around the crank flange situation by just getting the flywheel drilled to suit. i'd do it myself if i had an indexing head and a decent pedestal drill. if i can get some accurate marks on there i can do it. may as well get a spacer, pilot bushing and longer dowel machined while i'm at it. (the lathe at work is terrible)

    things are looking up.
