Gearboxes

[millworm]

I've got a 1200 5spd nova and was wondering what gear box it'd be and/or would I be able to swap it for a close ratio sr box?

Yes so long as it's not late 1.4 sr Sri I think as there bigger

it is an f10/5. it will be an economy box WR, most likely with a 3.94 diff.

the 1.3 sr box was always an f10/5wr with a 4.18 diff.

you will be able to fit an f13/5cr box straight in (as long as it has a mechanical speedo drive.) the f13/5cr usually comes with the 3.74:1 diff, and the top gear is the same as the old 4th gear from the f10/5wr box.
