Hi Andy,
I'm making my own, I was given a 2.0l pinto from a transit and it came with g/box and prop the best bit is the transit prop has servicable joints so im making my own also the transit spline is the same as for a type 9 and the rear flange fits my 7.5" sierra diff
I just have to decide whether to use the big tube or the small tube which has the centre bearing
just to say I've modified props before and never had any probs.
just make sure it runs true before final welding and that the joints line up with each other
