Look at the tag on the rear cover. It will tell you size, ratio, LS or no.

Yeah I didn't believe it at first either. While changing the rear diff lube I checked out the axle tag. Counted the bolts too, and all indicate a 9.75" rear.

Edit: here's one of my threads https://www.f150online.com/forums/ot...-axle-tag.html
