I bought a 1985 350X and the back of the crank case had been liquid welded, because it got cracked, there is a little bit of oil coming through. the guy i bought it from didn't say anything about it when i bought it, and has given me a lot of headaches because he is not very open to helping me out, but finally after alot of convincing he says he needs a tranny from an 1986 and he says he will give me the crankcase from that, but doesn't know if the diferent years will match up, so i was wondering if anyone out there could let me know if the 1986 crankcase would fit on the 1985 motor. thanks
