I have a freshly rebuilt C6 from a '78 Bronco and was wondering if all the guts are the same and could be taken out and put in a C6 housing from an '87 Bronco that has the smaller bell housing for a 302? Someone wants to buy my C6 for his '87 and would like to know if the swap is a direct one and how much would a transmission shop charge to swap over the internals?
I posted this in the transmission forum too but I posted it here as well seeing as how both transmissions came from big Broncos and because the guy who wants to buy my tranny needs info soon.

 

I'm pretty sure the small block c6 uses a different drum behind the pump.
