anybody know where i can get ratios of the bc gearboxes fitted to escorts?

with my current rebuild , i may want to get longer legs out of my current box

 

they are all pretty similar, with a 0.82 fifth. S2 uses a 3.82 final, u can swap this for a 3.55 from a carb 1.6 escort.

 

A reply i done a while ago, when i was deciding ratio's for my xr2tt last Nov.
