Thanks Chris!
I currently have a bellhousing from a Mustang II that I will modify as necessary to get it to work with the stock Pinto clutch cable. I do have a T-5. It is from a Fox body Mustang with a 4 cyl. If I have to end up using a V8 T-5, I will get one of those, but I think the ratios in the 4 cyl version would work better for the V6 on the street.
I have a lot of other things to do on the car first, but when I have the time, I have an extra engine I can use for mockup.
