I found a 96 Fleetwood in the junkyard with the map light mirror and of course took it. I note that this 94 FWB I'm working on doesn't seem to have any wiring to directly support the map lights. We're also considering running power to the top of the windshield for hardwire installation of a dash cam and Valentine One. I noticed that the front of the headliner seems to be quite significantly molded and stiff. What is the best way to lower the front of the headliner without damage so wires can be run up to the top of the windshield area for accessories? Thanks.
