I have a 1965 Mustang coupe with an incorrect C4 in it. It is a C4 from the 1970's...I'm not sure of the exact year, but if someone needs the year to answer my questions, I can check the case and provide that information.

I found a 1966 "green dot" C4 that I just had completely overhauled (at some great expense). It is much more similar to the original C4 that came with my car, and I want to put the 1966 C4 in and take the 1970's C4 out. Here are my questions:

What is the difference between the outside shift lever on these two C4's? I'm talking about the lever that sticks out of the body of the transmission and attaches to the linkage that connects it with the shift lever inside the car. I have reason to believe that the INTERNAL LENGTH of the transmission's shift lever is different, and there might be a chance that the shift lever currently attached to the 1970's tranny might not work in the 1966 tranny. Is this true? Could the shift lever on my 1970's tranny be THAT different?

Actually, I will have to swap the shift levers no matter what...the 1966 C4 has a COLUMN-SHIFT lever attached to it, while the 1970's C4 has a lever designed to work with floor shifters...I guess the question is: How likely is it that the floor shifter-type lever in the 1970's C4 will work inside the 1966 C4? The shift lever in the 1970's C4 seems to work perfectly with my car's shifter linkage...I am even wondering if the shifter on the 1970's C4 is my car's ORIGINAL shifter, swapped into the 1970's C4.

Also, what about the bellhousing? Will a bellhousing that fits a 1970's C4 fit a 1966 C4? My engine is a 289 V8 that uses a SIX-bolt bellhousing. The bellhousing on the 1970's C4 that is currently in the car SEEMS to mate up with my 289 perfectly well. So I'm assuming that the bellhousing will also mate up with the 1966 tranny. (The 1966 tranny has no bellhousing of its own.)

Thanks for any help someone can give me with this MOST confusing issue! Also, let me know if I am not being clear with my questions...it's late as I type this!

The 1966 tranny I have was originally mated with a 289. I will also be using a 289 with this tranny. Is there still a chance of the flywheel diameter being a problem, or do all 289 engines pretty much use the same flywheel? The reason I ask is because I intend to use my same old flywheel with this 1966 tranny.
