Was rebuilding the air shocks on my 82 Aspencade and discovered that one of them had serious grooves in the part of the shock where the seal rides up and down. Now I know why the rear was leaking. Oh, I installed Progressive's replacement springs, can run the shocks flat now if I need to. Like I said, I only need one, but if someone has a pair they don't want to break up, that's fine too. They're all over e-bay, but I feel the folks on this forum are much more trustworthy. Thanks
