can i put a V8 904 bell housing on a V6 904 and bolt it up to a 318?

i have a /6 904 that i know is good, and v8 904 thats been sitting outside and looks like a few critters crawled up in there. (PITA to clean). Im putting a 318 in my duster and was wondering if i can just pull the V8 bell housing off and slap it on my good v6 904 then bolt it up?? Save me SOOOOO much time so hopefully i can.

lemme know THANKS!
