a nice drivers side exhaust manifold from a 1969 Charger R-T 440 6 pak car. removed from a roll-over back in 1974, this is pretty much all that was salvage-able. been stored inside on a shelf since. 2843992 with a date code of 5 20 P. seems to me the 'P' should be a '9'. no idea why ma Mopar did this. this manifold number is correct for 1968 and 1969 B body cars with 383 4 speed, 440 and 440 6 pak only.
