Air bag separating???

[ca180]

I've got an 81 that I was planning on bagging. I bought a bunch of the neccessary stuff from a guy down in dallas and he sent me some used bags with all the other stuff. Anyhow, There is some separation going on where the upper part of the bag meets the lid. Obviously this is probably not good, but realistically how much longer will they last? I inflated them to max psi with no problem and let them sit a couple of weeks and there was no deflation, but there was also no load.

Just wanted to see if it would be worth running them for a little while. Haven't driven the truck in way too long and I'm starting to get ancy. It will soon be parked at my dads house for a few years because I'm joining the air force. He doesn't want the bags on there because of the terrain of his property so they will end up coming back off before the 12 hour drive to alabama. And I don't want to spend the money on new ones right now because I'm sure after four years they will more than likely be dry rot and I will have to buy them again... that would suck

Anyhow, I'm sure I can guess what everyone will say, just thought I'd get a little shove in the right direction before throwing them out....

Thanks guys
