GAS TANK STRAPS REPLACING

I've got a 1985 SVO and one of the gas tank straps just popped due to rust (scary). I have two new straps to replace both. However they did not come with instructions. Anyone know how to remove the straps? I know they bolt in on the one side, but the other side is my concern. How is the other side removed for replacing? Any help is greatly appreciated!

PS. I know this is the 5.0 section, but there are more people here and I figured there is a better chance someone on here will know. I had an 86 5.0 for 14 years, sold that and now have an 85 SVO. Gas tanks are the same as far as I know.

Thanks, I found the pin this morning and knocked out that side without a problem. However the bolted side of the strap is giving me a problem. Its apparently screwed up into a mount on the other side of the frame and now its just spinning, the screw will not come loose. I have no way to get up around to the other side to hold the mount from spinning so now its turned into a bigger problem. Time to bring it in to the shop.

Thanks for the help though.

Anyone know what type of mount these straps are screwed into? As I said in the previous message, the screw holding in the tank strap unscrewed about 3/4 of the way. Then felt like something broke loose and whatever its holding onto on the other side is now spinning and I cannot unscrew it further. Whats worse is I began to smell gas at the very end????? Did something snap on the other side of this and puncture the tank?
