rear leaf spring shackle measurements

Does anybody have a chart that has the measurements of the bushings (diameter) that popular shackles use like chrysler, mustang, camaro,ect. I'm looking for some shackles that will fit my frame. I looked here and on the internet and can't seem to find this info.

 

mine are 1 3/4 outside with a 1/2 hole

 

The deal is the frame I have has holes 7/8 in diameter for the shackle. I've seen tons of shackles on the web for sale but can't find specs on them.
