Question on Bilstein shocks

Final word: On another thread, I managed to find out the story about the upper bushing diameter.

The correct Bilstein shocks for Mopar A-body are the following:

Front Shocks
Part number: 55-R082
10.5” collapsed height
15.75” extended height

Rear shocks
Part number: 55-R092
14” collapsed height
22.7” extended height

For some reason, PST supplies 55-R093 for the rear, instead.

55-R093 has the same exact specs (Collapsed/Extended length) as the R092 but the eyelets/bushings are different diameter (upper eye is 5/8" instead of 11/16"). This is why I had to drill out the upper bushing.

If any PST people are following this thread, I hope you can correct your listing.
