Ok through research I found that the measurements are exactly the same for the KM132 transmission. Those bushings are still available for about $30. If anyone looks at this in the future just look for KM132 extension housing bushing. The bushing reference # is 362066 and MITSUBISHI-62. It's still super rare but I think I found 2 places with them. Drivetrain.com and Allstategear.com. 1.420" ID X 1.580" OD X 2.297" length or about 36mm ID x 40.1mm OD x 58MM length. The V5MT1 bushing seems to be about 3.8-4mm bigger ID and OD but the same length in case anyone needs that as well.
