I really lov them Hogs heads, they offer an inexpensive way to install late transmissions to the early blocks. Both theT-170 and the T-5 with a simple adapter plate. However, If you want to install a T-5 behind an 8Ba style block, theymake a simple inexpensive adapter plate to do that sa well. It bolta uo the Passenger car bell housing, both cast and stamped steel. Thus you can use the stock clutch linkage. Richard from fla posted a series of pics on this simpet conversion. I have to get the name of the company tat makes the adapter. I used to make them.
