Are both 52" and 56" spring SHACKLE bushings 1 3/8"

I have an 86 lwb GMC c1500 ordered with 56" leaves and hd brakes. My question is are the spring shackles the same for all leaf combos. I know the 52/56 differ as far as eye bushings but it seems that all spring shackles are the same.

Yes, they are the same. Aftermarket replacements may differ though.

Thank you bucket for the quick reply. My driver side shackle bushing is shot and it's riding on the sleeve/bolt.
I just want to order the energy suspension replacement bushings and only see them in 1 3/8 which made me think they must be the same for both length spring.
I admit a measurement would have been advised but you saved me from having to remove anything to measure....thanks again
