unfamilia 1,938 Posted May 27, 2015 Cause you guys actually answer questions unlike other forums thought I'd ask here I've got a new diff to Install. There are 6 different pinion flange combination and finding out what mine was from is nigh impossible to find matching tail Shaft flange. Mine is a round flange with a square bolt hole pattern of 72mm diagonal spacing. tail Shaft I have is 70mm diagonal spacing. This Is diff Shaft is from. Called a couple diff shops and they said just offset drill new holes through the flange 90 degree off from where they are now. They advised as the tailshaft flange has a locating rib to engage the pinion flange it will be centered so no need for balancing. $200 for one shop to do other said diy as it's a 5 min job. Any one done this here to offer advice? diff center is already installed in housing. torqued and shimmed to spec. I don't want to up set that. Share this post Link to post Share on other sites
slydog 7,873 Posted May 27, 2015 Why can't you get a tail shaft from whatever the diff flange came from ? Like whats it in now and what did it come out of ? Share this post Link to post Share on other sites
dougie77 789 Posted May 27, 2015 So your saying your pinion won't fit your flange sounds to me like you either need a new wife or you need to see a doctor whatever is cheaper 1 unfamilia reacted to this Share this post Link to post Share on other sites
