Dash assembly

The standard inst' panel is a cakewalk by comparison. R&R the rally panel is not something you'll want to do repeatedly. I suggest you do everything you can do before you put it back. Not only the inst' voltage regulator, replace all bulbs and sockets also. Then there's wiper pivot/linkage service, etc... The standard/non a/c climate controller has a plastic piece that is prone to breaking. If all those cables don't operate their doors easily, graphite lube, replace the plastic stem in the controller with brass, anything and everything that will keep you happy moparing for years to come.
