They are some off brand 32x11.50-15.Haha! My 77 has never been registered since I’ve owned it.
Honestly it barely ever has left the yard but a few times to stretch its legs.
What size tires are on yours? Look like 31s
I just measured the body line today and it is sitting 2.5” higher in the back. The front springs do not look happy with the big block.


I’m going to try, just haven’t got a chance yet.
