I like the looks of the '66-71 swept line trucks, but not the suspension and power assisted steering. I owned a '68 3/4 ton 2-wheel drive camper special. It was originally a 383 engine / 727 trans truck. When I bought it (only $300) the 383 engine had thrown a rod, and the body had plenty of dents, but only a small amount of rust. Main reason I bought it was just to haul stuff with, and it had the Dana 60 rear axle with 4.10:1 gears and 16.5 split rims.
At this time my '73 Sno-Fighter was getting pretty worn, so I took the built 360 out (replaced it with the original 318) and sold the '73. Then put the 360 and small block 727 into the '68.
I sold it to a friend whose wife liked it, and she kept it after their divorce, but I don't know what happened to it since then?
