Hey everyone I’m having a new driveshaft fabricated for my 68 XR-7 with a C4. It was recommended that I purchase a new yoke. My original yoke is a 28 spline and has a counterbore on the end to accommodate the spline seal. In my shopping around I haven’t found an aftermarket yoke that offers a counterbore. Does anyone know if the counterbore is necessary or can I run a yoke without one?
The modern end seals are shorter so no.
