oops stitch i have a similiar ? i just posted.
if a mod reads this i wonder if i could post a question & compile any/all rear end width, gear ratio, posi or not etc. that members have in their trucks wether stock or not.......maybe a heading like "Which rear end will fit your truck" using a format that a member will fill out, what does the moderator think about this for the FAQ . i know there's scattered info here but like i mentioned nothing popped up when a either lookked in the FAQ or did a search for rear end ratio's
