Technical Really? Another t-5 question

I posted the other day and have not found any reply so will ask again, I am looking for a Ford bell housing that will bolt to a 351ci Ford (about 1970) that has the bolt pattern for a T-5 out of a 1993 Mustang with a V6. The bell housing that came with the transmission is longer and deeper at the top than the one on my old 4 speed. I am hoping to find a bell housing that is 6-1/4" from the face of the bell housing at the block to the face at the transmission. Any one have any suggestions?

 

Tom:
Nobody is replying because what you want does not exist, but a few jumped in to try and help. The input shafts of both the non-world cl*** and world cl*** T5s are longer than the old toploader and T10 shafts, hence the bellhousings are deeper. Where do you expect that extra input shaft length to go with a shallower bellhousing?
