are the transmissions from the 87 Si cars different from the 88-91 Si cars? My 91 CRX is gonna need a tranny soon, the bearings are getting pretty noisy. I don't have the time or the work space for a rebuild, so I gotta go with a swap.

I have an excellent-condition 87 Si transmission, out of my housemate's car. Will that gearbox fit into my car? The gear ratios seem really similar, if not identical to my own car. thanks
