PH is right as the frame you have is not a convertible frame with the factory boxing. You have a channel frame that appears that the previous owner simply left the transmission crossmember bolted up to the frame rails, notched a section to go over the top of the crossmember, then secured it in place and welded it up.
The problem is of course you can't get access to the nuts on the other side of the bolts UNLESS the guy was smart enough to have welded the nuts in place on the metal plate holding the rubber mount that the flat end of the crossmember slides into. I would try to unbolt it first to see if the previous owner/fabricator used any forethought in his construction.
You could use a sawsall as PH suggested and cut the crossmember flush with the side of the boxed frame. Then you will have to fashion a bracket that will go underneath the crossmember end, which will have to be welded to the frame.
I don't know if you will have enough material at the end of the crossmember to use that factory type mount/rubber isolator. If not, then I would drill holes through the bracket/crossmember because you will be cutting off the flat tab/ends found on the crossmember. I would find a round rubber mount ( or cut up the factory isolator and use a portion of it) that will be about the same thickness, and place it between the mount and crossmember end, run a bolt through, and use a lock nut to tighten it down, but not to the point you crush the rubber mount and it has no absorbing properties.
Just an idea.
The attachments are for example only and show the mount like yours found on an open/non-boxed frame and the other shows a boxed frame with mount for the crossmember welded to it.
