I did exactly that, Rick. Not too big a deal - completely cut out the old a-pillar and cross tube, pull the dash back a bit, bend up new a-pillars, and trim the dash. The trick for me was to use tube connectors under the level of the dash to allow the cage to be removed without completely removing the dash.I wonder what it would take to swap the front stanchions to a thru the dash tubes? Or if I could do that?
Of course might be easier to get a whole new cage made. I like what you have done with that PS cage.
