I find em all the time, I just dont have the money to buy em all
Here in Mineola I know of at least 8 that are driven most of the time & have pretty nice paint
I currently own five 67s & my dad has three 67s, a 69 burb, a 68 & a 72
So I dont think they are hard to find... not as common as square bodys, but still a lot of em out there
