OK well the tranny finally came out and upon inspection it was none of the above

Fourth gear is gone... The countershaft and the main shaft and the gears themselves are galled beyond repair which is so weird because 4th was the only gear that it shifted into and out of smoothly and didn't make any noise in at all but a visual inspection is the proof. I need a new one

I put up a thread in the wanteds and asked around a few months ago and kinda let it go because money is so tight and I'm sorry for that but now I don't have a choice

I gotta find a Mazda M5OD-R1 quick and $500 for a junkyard tranny is redamneddiculous. So 1. will a M5OD from say a 2.9 bolt up to a 2.3 or are they different? or will any? 2. Does anybody know where I can find one nearby for cheap? I'm about an hour from asheville, NC and I can't afford to drive more than a couple hours out so any further and it'll have to be shipped. Any help is greatly appreciated
