You _can_ do it without welding and without special fasteners, but it
requires a bit of ingenuity, some epoxy, and some not-so-friendly (read
this as frustrating) work through a small hole in the frame.

Say you wanted to put two bolts into the frame about 3" apart. Drill
them, and de-burr the inside edges -- you'll want the inside smooth.

Using your bolts as guides, epoxy the appropriate nuts to the appropriate
washers, and let them cure.

Drill a third hole between the others just a tad larger than the diameter
of the washer for that bolt. Smear some more epoxy on the open face of
one of the nut/washer assemblies. With curved forceps or just a curved
wire and magnet (glued to the end!) hold the washer the inside of the
buck while you screw in and gently tighten a bolt. Do to both. Prepare
yourself for losing one or two down into the cavity (DAMHIKT). Let the
epoxy cure, then remove the bolts.

Be gentle when first starting the bolts in again so that you don't break
the "backer nuts" off the inside wall.
