Is it 100 percent 60mm. I've heard verious different size's now.

I called abc motorsport yesterday, to see if they would do the prop for me,according to fast ford magazine they are big in the rwd escort cosworth scene.
But they said they got it done by another company and said i'd be better off finding someone else to do it.... I couldn't even get an answer out of him on how much to remove as he couldn't remember. Chusdy!
