It may be possible to use a nut splitter to break off the nuts saving the original carriage bolts. Not the new style but the old style. You can buy a vintage “Nutsplitter” by H.K. Porter on eBay which is what I have. I have used it numerous times on my truck. The cutting edges on the tool can be rotated so the tool can be inserted between the channel. I looked at my truck and the tool and it looks like it will work.
