Hello everyone, I am interested in purchasing a Fiesta paddle clutch for my 1.9 CVH engine, however, I am using an American 89 Escort GT MTX III transmission. I am wondering if the Fiesta RS clutches would allow the my transmission to slip through. How many splines do the Fiesta RS transmission shaft have? There are no performance clutches available for the american escort before 91. Wondering if anybody could help? Thank you
