John,
I'm going to fab up my own mounts. Most likely use some angle or flat steel on the bottom of the frame rail. Then some 3/4" ID round tube welded to it. That will allow me to put a 3/4 bolt or pin through it. I'll do the same on the fiberglass front end, then fiberglass the metal to the front end.
The bolt/pin will most likely have a set up like a tow hitch where you pull the lock out then the pins and can lift the whole front end off after tilting it.
If you want, it will most likely be pretty easy to do, I could probably slap a second set together after I do mine.
