I know the splines on the input shaft are different. They depth of the input may be different also.

Even though it's a T5, just about everything is different between the Ford box and the GM box. It won't bolt up to anything but a GM bellhousing.

In case you didn't know, it might be easier and cheaper to install a 4 cyl. Ford T5 in your GT. All you need to do is keep your stock V8 bellhousing and use a pilot bearing for a mid 80's deisel Ford ranger. it even has more aggressive gearing, acting like a small rear gear swap.
