Help with Leaf Shackle Bushings

Killer6 said

Those calipers are reading 13/16", the bushings should fit the shackle bolts/studs tightly, they slip in the eyes relatively free. Usually there is a bit of gap between the bushing
shoulders and the leaves, when you tighten them they compress and "fill" the eye snugly. The eye and hangers on my '64GT are .880"ID, it is a /6, so IDK what those fit at .812".

My 75 slant 6 had 7/8 also. These were too small. Hoping they work for OP. My front Eyes apparently were an oddball. Had 9/16 bolts in 2" eyes. Every other reference I have seen said either 1/2 or 5/8?? I had to change front hangers anyway, so change them to 5/8 bolt that fit new bushings I got.
By the way @1965t5 I have a set of Energy Suspension 1.5" bushings for front eyes also if you need...
