After reading what you wrote I have some doubts about it since you mentioned about the pinion spline is 28 in the 71’s and 30 spline in my 67. Can you give me your opinion on this? The gears are Nos and the posi is rebuilt.
I put in a 421 factory motor from a 66 2+2 with 3x2’s and stroked the motor bored .060.
Thank you
He is correct , just use the 71-76 yoke on pinion with 71 gears and posi , as far changing u-joint and or driveshaft length pretty sure its just a conversion u joint at worst may not even need to do that
