OK, I think I'm ready to try a pointless ignition for my 292 c. i. (from a '61 but installed in a '54 Merc) but I have no knowledge of these systems.  Which product does anyone have?  How hard are they to install?  Do they take care of advancing the timing or do I still need the vacuum advance?  If this has been covered before, which I imagine it has, just point me in the right direction.  Thanks,
