Is there a easy way to know which rear end it has. 97 F150 4x4? 8.8 or 9? Can't find a tag anywhere. The plan is to purchase a used one and swap. Only need the rear one.

If it has the 5.4, then it has a 9.75
Otherwise it will be an 8.8
Swapping rearends is easy. I did mine before Christmas. Took less than a day laying on my back in the driveway.

Look at the door code. Im not sure all 5.4 motors had the 9.75 rear end... SCREWS yes, but regular cabs, im not sure. SEe if we can get a picture of the pumpkin cover bolt pattern
