I am replacing my gas tank on my 1950 3600 truck. The old straps were basically rusted off, so I just used some tin cutters to release the gas tank. Now I have the gas tank out and am ready to put the new one in with new straps. I'm drawing a blank as to how to remove the old straps. Are they welded to the floor of the cab and the rear of the seat frame part that's welded to the floor? I tried prying them with a screwdriver and it wasn't budging. The new straps look like they would be more likely to bolt in, or else they just slide in place. Can anyone solve this riddle so I can get this finished up and put the new tank in? Thanks!

Do you by chance recall where this might be? I looked on the new one and didn't see this, I guess they expect you to reuse the old cotter pin.

It appears from your pictures that the brackets may be riveted or spot welded to the floor where the holes in the new brackets are. If you clean up those areas on the old brackets you may be able to determine the mounting method used.

Now I just need to work out how to get the bolts out. Unfortunately they didn't use something simple like a cotter pin, instead there is some black plastic washer looking thing holding the bolt in place. I tried knocking it out with a hammer to no avail, tried using a screwdriver to snap the plastic washer, still to no avail. I hate damaging new parts but this thing is about to get some Dremel action done on it if I can't work out how to get the bolts out!
