My presaftey work is coming along nicely, front end work is almost done new shocks new upper ball joints new tires just need the new intermediate steering shaft boot to wrap up. Then on to rear suspension where I see I have ac delco shocks that look quite old so will probably replace just wondering if the delco shocks are the original type and if they still make them for our GMC,s could not find the shocks in the online parts exchange. I see lots of discussion on the KYB AND Bilstien shocks but no other comparable brands eg Monroe etc. I see most do not offer life time warranty but they are locally available

That's what I figured as I could find no numbers for the delco I ordered new kybs as I am pretty sure the delco would be toast

Folks here have said the bushings won't last, and they replace them with urethane bushings. I searched the forum for urethane bushing and polyurethane bushing and came up with one part number, but I think it takes two different part numbers to fill all 8 mountings. I thought I had the source bookmarked, but can't find it anymore.
