Your red 67 4dr/4spd Fury was on ebay recently (as you probably know).
Don't fret on selling the shortram parts with the car, at the last few years of my local Mopar-only swapmeet there has been quite a bit of crossram stuff, and I'm not seeing it sell (there were 9 sets of ram intakes, and 3 or 4 near-complete assemblies in 2016). So letting it go with the car is probably the best choice for the car. IMHO, I don't think there are many guys actively wanting to buy that stuff anymore, I think the Letter market is in a permanent downtrend due to age/demographics. I think the 63-4 shortram car market might be going up, but only as a bargain compared to the 60-62 cars, and then just for the cars with the rams complete/installed/RTG. (simply based on ebay, anyway)
Cool collection of cars, love the gold on that Polara, but I gotta say - that's the weirdest friggin' set of trusses I've ever seen in a garage!
