Help! I need some diff pinion flange dimension clarification!
I recently ordered a custom aluminum heavy duty driveshaft from a reputable vendor, but it doesn't fit. I have a early 260z with a r200 3.9 diff. When I installed the diff, it did not come with a pinion flange. So I installed a pinion flange (the square one) from a 280z.
My current pinion flange has the same dimension as pictured in the left. My replacement driveshaft has the dimension as the one pictured in the center.
So, what is the diff pictured in the center from?
Thanks!
