Bump!
The ratio in a (1983+?) 4spd 1.4 is the same, but the casing is different - it's longer, to compensate for the missing 5th gear section. I guess you could swap the internals, but that sounds like a lot of hassle!
The diff is identical to the one in an injection 360, though. Carb 360s had a taller (higher ratio) diff. The 3.64:1 diff from the 1.7 and 2.0i are the most common ones, so you should be able to find something without too much trouble.
