In MY driveway, I'd hit the bolt with an impact wrench just for giggles, and if it didn't immediately spin out of that clip-nut,
the bolt would be eaten alive by a die grinder and abrasive wheel. Naturally, I'd make sure the gas tank fill tube and cap were in place, and the vent hoses connected so the sparks from the grinding didn't ignite fuel vapors.
For fuque's sake,
don't cut the strap (expensive) when
bolts are cheap and easy to source.
The clip-nuts are available at any parts store in America...if you know who to ask.
Some of those clip-nuts have a special shape to the clip that's tougher to find. When I replaced the leaf springs on my Nova, two of three clip nuts on one side were damaged. I had to fix one, and fabricate another clip and braze a nut to it; there weren't suitable clip-nuts available without substantial order-and-wait delay.

(The middle clip nut got a better braze after the photo was taken.)
