George,
On my PV, the only thing that was left of the radiator blind was that bracket (?) that holds the roll, a piece of rotted cloth, the wooden strip that held it down, and a few feet of chain. I found the luggage compartment cover of a Bronco II, cut that down to size, reused its roll-up spring mechanism and fitted that into the pull-up bracket. The rest of the installation was straight forward. My main problem was finding a chain thin enough to fit through the places it's supposed to go through. The one I ended up with is still a little too thick and rough to move smoothly through the bulkhead and fit into the latch under the dash, so I reused the piece of original chain there and attached that to the thicker chain, which moves all right through the little tube on top of the radiator. It works fine, but is mostly a conversation piece because I don't drive the car in winter.
