I am converting my 73 challenger back to a 4 speed (A833) and looking for bell housing. I found one on ebay but the guy is not sure if it will fit a 440. the casting number is 2468370 were can I find info on this bell housing ? He said the bell housing is from a 1965 B BODY 361 OR 383 BIG BLOCK 10 I/2" CLUTCH thanks
