Do you know if it was originally a Cali or Federal HF? It matters because the Cali HF had a 3.25 final drive, which was the same at the VX/CX in the 5th generation. Though the CRX HF had slightly taller 4th and 5th gears, it is not a radical difference from a 5th Gen VX/CX:

The HF trans can be mated to the 5th and 6th gen D-series engines, but with a little more difficulty because of the need to convert from cable to hydro shifting mechanisms. So how different the gearing is from the VX/CX matters...
Also, what price you asking?
