Any one have info on shoe horning a t-56 into a E-body?

I know i will using a 18 spline Quadzilla made by RSG. But where do i find the appropriate bellhousing, it is going behind a 440. I know its been done but finding real useful info about it is hard.  

I am hoping to do the same thing. Did you ever find any info?  

I did find a bellhousing adapter at http://www.wilcap.com/426T56.PDF at $750
if interested. It is for a 426 hemi but that should have the same bolt pattern for a 440.
