What ball joints do i have?

[demonjohn]

Hi,the 72 Demon i have,has a lower ball joint 7181FLH.I'm new and not sure if this has been swapped for 73 up or not.I can't tell if this is small joint or big one.Any help would be apppreciated.It also has the big bolt pattern if that matters.

Thanks,John

The lowers are the same for new & old. The uppers went to large in 1973. If the calipers are on the front side of the rotor, you have the larger ball joints. if the calipers are on the rear side of the rotor, you have the smaller upper ball joint. If you have the 4 inch small bolt pattern wheels, more than likely you have the small upper ball joints.
hope this helps
