Let me preface this with admitting I don't know much about Ford Transmissions. I just bought a C4 Transmission that based on the numbers originally came out of a 1968 Mustang. I want to put it with my 260 engine and already have the 5 bolt bell for the swap. Today while removing the old 6 bolt to put the 5 bolt bell on, something doesn't look right. For one, the old 6 bolt bolted onto the the outside C4 case. The 5 bolt only has the bolt holes to bolt onto the inner transmission. That and the fact the the 5 bolt bell is TIGHT to get on and seated up against the transmission is another question. After trying to help it on with a mallet, I'm close, but still not tight against it. I've attached some pictures to help explain what I'm talking about. Am I missing something?
