Need a quick help on gearbox!!!

[CVC]

Does the gearbox from CRX d16z5 (1991) fit to CRX d16a9 (1989)?

It seems that gearboxes on both engines are L3, but full part numbers are different.

And one more question - where can I find gear-ratios for these gearboxes? Or maybe somebody know which gearbox is shorter?

I've just found the following information:

CRX 1989
d16a9 -> gearbox # L3-010
d16z5 -> gearbox # L3-010

CRX 1990-1991
d16a9 -> gearbox # L3-020
d16z5 -> gearbox # L3-020
