U Channel 1/4" Bolt Removal

Can you share the best way to remove the U-channel bolts? Mine look like cheap stove bolts with square nuts with a good inch of very rusty threads. There isn't a lot of side to side or vertical clearance for tools.

I can see this being a royal pain, even with the inner skins removed. I am replacing the back two feet of rotted bathroom subfloor.

Grab the sq nut with a pair of vice grips and wiggle it, it will break off.

I had a few on my 68 that would not break off as Colin and Vernon suggested. I did remove most of the bolts in that way but on a few tough ones a 4in grinder with a cut off wheel worked well.

Thank you for the tip. I'll grip the square nut and pry hard to break the fastener. I'm sure the rust has weakened it quite a bit. The rear frame to shell support angle iron is solid and in good shape. It should support my bending forces as I try to break the bolts.

I'll let you know how this all goes.

If that does not work, you could always drill off the head of the bolt from the other side.

Well, I wiggled six of the stinkers until they broke. Great fun! I felt like a dentist, except I didn't get $300 a pop for "extracting" them. I have one that I am going to have to cut or drill the head from underneath. But for the most part, what I need removed is done.

Thanks for the great tip. Wiggle Wiggle.

With the exception of the end cap channel the rest is easy to replace at any ac fabrication shop and usually it cost 10 to 20 bucks for an 8 foot piece. Nice pictures keep them comming.
Later cliff

Wiggle till they break, if they don't I use a dremel tool with a grinding wheel, gets into the channel with no problems. Sawzall with a short blade might work too, if the channel is loose enough.
