Looks like its a 8 3/4
Crawled under the car yesterday after Spring Fling, it is solid in the rear, and has 10 bolts in the front around the spline area.
Did a search, and couldn't find the answer. So I have to ask.
How can I tell if I have a 7 1/4 or 8 1/4 or 8 3/4 axle ?
Where are you measuring from, or can I find it on my fender tag?
Thanks all.
