83 Urq tranny compatibility w/4kq?

[Louis-Alain Richard]

Swappable, sure. Physically at least.

But there is some difference:

- Final drive ratio, 3.89 for the urQ, 4.11 for the 4kq.
- Some gears are different, as the 1983 urq has very short first and second
gears, then a hole, then 3-4-5 are closely spaced. To resume, urq 1983's are
6 speed gearbox missing the 3rd... 4kq are better, more envenly spaced.

I forwarded this message to Martin Pajak, he's THE reference for this kind
of question.

Martin ?
