How do i know what rear axle i have?
« on: August 01, 2013 - 01:56:19 AM »
got a 70 barracuda with a 318. How do I identify the rear axle? Would it be a 8 3/4? What are the different case numbers?

Look for numbers on the side that end with 741, 742 or 489.
The funniest thing about this particular signature is that by the time you realize it doesn't say anything it's to late to stop reading it.

Also this can help if you can't find numbers. Just count bolts on the pumpkin lid or notice that it is front opening only (8 3/4).
