70 C20 CST Custom Camper Longhorn big block (and a good example of how to not take pictures for an ad. Not a single one pic of either side of the truck, just a bunch of extreme close ups). It "could" be nice, but you'll have to ask for more pics or go visit to know for sure. $10.5K
Also note, "selling for a friend, but contact me" note - it could be a very nice truck, but I'd look in person if I were interested.
I don't ever recall seeing the aftermarket saddle tank bedside fuel tank doors ever straddling the vertical Longhorn split line... interesting.
