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 class and world class 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?
