1966 valiant worth getting a 230 (or 240 can’t remember the numbers)

Get a 745 transmission that came behind the 273 (and some 6cyl's) that year. That should be a bolt in and your column and linkage might work with minor mods. Even the yoke is the same and maybe driveshaft length. It's a stronger trans than the 903, but not quite as beefy as the 230 or 833, which will need more mods to fit. Forget the 250, it's not much stronger than the 903 and I think has a different front bearing retainer.....or maybe it was the bolt pattern on the bell housing.....I forget. Isn't worth the swap anyway.
