T5 swap to a 225 Slant 6?

Ok, so I've seen a lot of guys run this swap of small and big block engines in A Bodies, but I've yet to find any info on someone doing this to a Slant 6....
I've bot the basic ideas covered (input splines, input shaft bushing, cross member mod, driveshaft yoke, etch)
Can't seem to find a bell housing though....
I was thinking about adapting a 4 speed belt housing though

Any ideas or thoughts?
