Re: help with 12 bolt info

You have to be careful going by how much someone else narrowed their differential. The early '70 and earlier 12 bolts are 62" wide. The late '70 and up are 63.5".

I know this doesn't help you but the correct way to determine the width/length of a differential is to start with your tires and wheels. Place them the distance apart they need to be and measure wheel flange to wheel flange.
