Need restoration tips, was the underside painted body color or black? The car having 151K miles on it is hard to tell was was original and what was modified for example the red grille inserts are gone, maybe taken off for another car.

can u drop the engine out like the other mopars by taking the K-member out?

I used to have a gunmetal U code Charger S/E.It was nicely optioned...tips ,tach,suregrip,air etc.The 73-74 B 's are painted pretty much the same as all the earlier B's...primer bottoms with overspray around the edges.Okay for a show poodle but if you are going to drive it I'd do the whole bottom in black.The K member does come out as a unit along with the isolated T bar crossmember.Might as well replace all the worn out K and crossmember bushings with poly pieces while you are at it.
