I am going to have the smaller bolt pattern drilled in my 8.8 pinion flange to match the smaller driveshaft flange that is currently in my truck. What size and thread are the bolts that are in it right now?
I figure I will have the flange out to change the pinion seal anyway, and when I get the 289 put in and have custom shafts made, I can go to the bigger pattern then.
