skid pan bolt up problems 78 CJ-5

i was attempting to remove the skid plate in anticipation of replacing the clutch a little later. the PO welded the plate to the frame and the bolt at the rear most passenger frame bolt. after grinding out the weld, i removed that bolt and the others (one of them broke off, i could kick myself for using a cheater), loosened up the plate except for the torque arm and found when i was going to bolt it back up that i have two i can use on the driver's side and none any good on the passenger side. three of them you can slide the bolt up into the frame as the nut assembly welded into it, or however it is made is gone completely, and the front most bolt on the passenger side is rusted into the threaded assembly in the frame and just spin the whole assembly, but will not tighten or loosen to rempve the doggone thing. since the frame here is boxed on all sides, and i know this is probably a dumb question, but how to i rectify this situation so i can bolt the plate back up to the frame? ther is nothing for the bolt threads to bite into and i can't get a nut in there, any and all suggestions are appreciated, including how to get the one wayward bolt out that is as useless as it can possibly be. i guess the PO's solution to this rpoblem when he came across it was to do the welding. that seems counter productive to me.

thanks in advance

Sounds like you'll have to drill holes in the frame. Or cut out boxes and patch it back up. That way you have access to the new nut.

I just had to do this on my 76 CJ5. Although, I had 3 good bolts on the passenger side and only 2 / 3 on the driver. I could have left it, but that one bolt bugged me.

Here is my fix.. I took one of those uni-bit drill bits and made a hole on the inside frame rail. I kept drilling a larger and larger hole until I was able to fit a small nut in there. I put the bolt through the bottom and really had a hell of a time getting a wrench in there to put on the nut.

Now there is a fairly sizable hole on the inside of the frame, and it isn't exactly in the center of the piece so I'm a bit concerned about strength. I think I'll weld in a patch so that the strength of the piece is not compromised.

You COULD just drill a hole up from bottom all the way through the top of the frame and put long bolts in this way. Since most of your bolts are missing, this would look a bit more "normal" than one like I would have had to do.

Get a flanged nut the correct size and a drill bit/hole saw the same size as the flange on the nut. Drill out the old nut.
Thread your flanged nut unto a longish bolt and place it in the hole you just drilled and tack it to the frame. Take the bolt out and weld the nut up the rest of the way.
No new holes in your frame. Just a brand spanking new nut.

I had similar problems not long ago. I ended up drilling a new hole on the top of the frame and ran a long bolt through the skid and through the fame. Just remember to use grade 8 bolts and washers.
