You could try Mata and RX7 gear boxes. Just use your cell housing and tail housing from you B2000 and you should be in better shape.
Also, the B2600i (aka type 3) transmission will bolt into the F2/FE blocks, but you will need different flywheel and clutch for it to all work. (I think MX6/Ford Probe 2.2L turbo flywheel, I forget)
