I made this swap on my '62.
The cable vents are a '60-'61 deal, in '62 they went to the hand lever style.
I found them in a junkyard truck and grabbed them. It's NOT a direct bolt-in, but close.
You'll need the vent assemblies from a '60-'61. Forget the cables, knobs and their mounting brackets. These are available new from LMC or other vendors--they're clean, shiny, not corroded, and actually work, so spend the money. They also come with the mounting brackets for the pull knobs.
the first thing you'll encounter is that the screw holes for the vent don't match up with the holes in the truck's kick-panels. You'll need to redrill new holes. Keep the holes small, because they attach with sheetmetal screws, and if you make the holes too big, the screws won't bite.
Then you'll have to mark a notch in the kick panel, for the cable to pass through. I didn't know that when I first did it. If you don't make the notch (under the louvered panel's mounting flange), the vent's panel will pinch the cable. I used a die grinder to cut the notch.
The cables/knobs from LMC give you plenty of extra length on the cable and sheath--you'll need to cut and trim both to fit. Trial and error for the length.
There are threaded holes under the dash (at least on my '62) for the knob brackets to screw into.
I love 'em... pulling the cable is a hundred times easier than trying to reach under the dash while driving down the road.
