Another bolt option, if you’re not going for a “perfect restoration” go get the correct size hex head bolts. Wrench on top and one on the bottom. Our 92 was that way when we got it. I thought someone was cheep or lazy..... but when we need to get to the tank senders, sent the oldest under with a wrench (he is 23 and it was his truck), me in the bed with the cordless ugga dugga and we had the bed loose in maybe 15 minutes.
