I have a mx83 cressy with a 1jzgte sitting in the engine bay. I want to know if my cressida tail shaft fits into the 1j box without any mods. I also want to know if I should use the 1j tail shaft yolk and modify my cressida tail shaft. Someone told me that it was illegal (cant be engineered) to cut and weld a tail shaft and that it will never balance properly if I do. Is this correct? Any advice would be appreciated.
