And what speedometer gear do you think I should use? My invoice shows that I have a 16T TKO speedometer gear. And where can I find a new driven gear? I'm running 285/40ZR17 -25.9" tires in the rear. My speedometer currently is around 5mph fast.
Thanks for any help/advice you can give me.
BTW I can honestly recommend doing business with BGH (Freddie).
I believe pinion yoke changed from accepting the 1310 u-joint to the 3R u-joint in '76 so the one you have should work.
