Hi!

I have a 1983 volvo 240 112hp, 5-manual gearbox. Engine and gearbox
in that car will be replaced with a B21 4-manual gearbox.

Questions:

1. Exactly where do I find the specifications for the gearboxes? I cant find it in haynes or on the papers for the cars. (M40,M41 - M45,M46)

2. Will there be trouble with the gear ratio on the rear axel, when a B23+5man is replaced by a B21+4man?

3. Any other details regarding this swap that I should be aware of and take special notice of?

Thanks for all your help, ideas, and thoughts.

All the best.

Daniel, Sweden.
