I am in the process of swapping the trans in my 85. I just rounded off the right rear cradle bolt. If i use a dremel to cut it off, how can i get the nut out of the frame?

Can you not use the dremel to cut two new flats on the head?If you do that, so an adjustable spanner fits on tight, and then heat up the bolt, you should be able to get it out.Probably need to squirt some releasing agent on the bolt first,leave for a while, and try with the spanner,before doing the heating bit!!Or else mig-weld a strong bar to the head of the bolt...the heat would probably release it too...but maybe your access to the area is too limited for these solutions.Hope I might have helped

I think you can cut an access hole in the frame and then hold the nut. Then weld a new nut in its place, dont leave the hole after your done weld the plate back in.

His nut is not spinning. The head of the bolt is rounded.

Try to cut 6 new sides on the bolt like FF said. You don’t have to make it perfect, just get it close. Then pound a cheap socket on it. (well not cheap, more like disposable)

If that doesn’t work then you will have to cut the head off.
Once you have the head off and the K member dropped use a stud extractor or something like it to remove the bolt. vice grips probably wont do it.
Use can use pliers like these if you can find them, http://buy1.snapon.com/catalog/OBJECTS/19200/19159.JPG
I have broken off 7/16 exhaust studs with them before, not that you want to do that, but the do grasp a round object really well.

You may have to pull the lower half of the back mount off to drop the K member if you are just swinging it down. The hole will probably bind on what’s left of the bolt.

Thanks everyone. Now i have a few ideas to try tomorrow.

If you're a good welder then you can weld a nut to the top of the bolt. The heat will also help free the bolt.
