The frame is not a big deal from what I have seen, or heard. After talking to sixb (dave) about it for awhile after he went with the big truck stuff. Said cost wise and ease of finding parts, cutting the frame is much simpler.
The other mount doesn't use an inexpensive compressor or even one that is easy to find.
The frame cut is much easier and it was the way he was going next. With yours being 2wd there is nothing out there that the frame supports except the radiator support and the bumper.
Cut the frame, not even sure I would box it in to fix cut and be done.
