Aluminum Housing OD 4 speed

So I'm thinking I really don't want to cut the floor pan on my car like I'd have to with the T5 or T56 or even a 200R4 swap. it's the cleanest I've ever seen on cars I've owned (minus my brand new dd).

I had an 81 D150 with the Aluminum housing 4 speed with OD and that truck averaged 20 mpg. Granted that was a slant six truck, but I was able to peel the tires and have some fun with it and not hurt the trans.

I did a little searching online and I can get a trans and bellhousing pretty cheap. Has anyone put one of those in their early A body? Will it work with the Early A pedals and Z bar? I searched on here and know you would have to modify the shifter location (read new shift rods and shifter). I was thinking I could make an offset bracket and position the shifter to use the A body linkages. I also know the driveshaft would have to be custom, but I'm not so worried about that as I plan on losing the trunion joint and adding either an 8-3/4 or 9 inch rear end at the same time.
