Ok so I have an 85 4x4 b2 with what appears to be a mitsubishi fm 145. I was able to get a good deal on a transmission from a 90 4x4 ranger and t-case. From all the photos and research ive done the transmission looks like a mazda m50d. I have not been able to find any information on a swap like this so hopefully someone can put their .02 in and give me some advice. Like if its a straight swap, if I will need to modify, or change other parts? Any and all help is appreciated.
