Chevy T5 in a model A

[denver9]

I have a Chevy T5 transmission in my model A and love it. Problem is I need to replace the transmission. I have been told that the 93 and newr transmissions had an integral bell housing (part of the transmission case) is that really true? I need to be able to remove the stock bell housing from the transmission and want to be sure I get the right one.
