in need of seat belt restoration / rebuild

Ok, I'm new here so please excuse my ignorance.

I'm finding it nearly impossible to find information regarding seat belts on '76 Stingray.

The belts in my car are in great condition however they stick and are difficult to pull out to put on and won't retract very well either.

I was wondering if there is somewhere / someone that can rebuild these things to be like new mechanically speaking?

Thanks in advance!
