The engine that Toyota used was not a 235, but rather a copied design. It's dimensions are different from the 235, almost more like GMC, really. Not sure about what bolt pattern was used for te bellhousing, though.
I'm with Jerry, with all of the 4 speds that are a direct bolt up, and even a few 5 speed overdrives that are easily adapted, why use a Toyota trans that really doesn't give much benefit?
