I should start this and say I know virtually nothing about transmissions, in the past when I've blown them up it's just been a re and re procedure for me anyhow I bought this transmission off of e-bay about a month ago
It's off of a late model 2.3 duratec Ranger/B2300 It looks to be in good shape and aside from having the correct bell housing it was gloriously cheap compared to my other options (about $150 vs. $800+ for a NC miata or to buy a bell housing to fit a T-5 could easily run you a grand or more by the time it's bolted up. The downfall of this particular transmission is the shifter location that will be hidden quite nicely by the scuttle... fine for people with five foot arms and multiple elbows and wrists, me not so much.
I've been looking online for solutions and while a home brew shift re-locator is doable I came across a picture and then an article with lots of pictures. http://www.tccoa.com/articles/mn12how-to/m5r2_rebuild/m5r2-rebuild-howto.html
Now to the best of my knowledge my trans is a M50D-R1 Mazda built Ford part numbered transmission. This other Transmission is from a Ford T-bird Super coupe, fitted with a M5R1 Mazda/Ford Transmission.
Looking at these pictures in my garage last night on my laptop all the holes seem to be in the right places to swap off the top cover and the tail assembly to make my transmission a rear shifter. Can anyone see problems with my logic on this??? If this is workable than this could prove to be the silver bullet to make Duratec builds more affordable.
