We had a few ideas on how we wanted to do the upper radiator mount, but it all actually fell together easier than we had initially thought.
We struggled a bit with a distorted hood latch panel before giving up and chasing down another (good) core support/latch panel today from right across town...I love it when a plan comes together.

A quick bead blast on the "new" old parts and we were done...almost. The inner lip of the latch panel perfectly holds the top of the radiator in place...couldn't have been any better! We ended up with a little less than the inch of clutch to rad clearance we were looking for, but still have plenty of room.
We will fit/weld in a bit of sheetmetal to hide the top of the radiator and then call it done!
