C4/FMX Driveshaft

[knn]

Does anyone know if the driveshaft is the same for a C4 and and FMX behind a 351c (H-code)?

Thanks

I don't think so. Length of the drive shaft might be the same but you need a different version of the slip yoke.

Output shaft C4 needs slip yoke with 28 splines.

Output shaft FMX needs slip yoke with 31 splines.

Thanks!

I think I have both yokes.

Can anyone measure their FMX driveshaft length?

Thank you
