Rear defroster for a hardtop without one

[Joe Blaze]

Can anyone recommend a solution to fit some kind of defroster to a hardtop that never had one. My '71 Blazer hardtop gets fogged up in the winter, and I want to put something back there that will clear it up so I can see out the back.
Thanks

Could run an aux heater...

I tried this:

other than that, I don't know. I don't think any of the 1st gen trucks had power back there, so aftermarket would be the way to go. from the link above, it doesn't look like it would be too terribly expensive.

Hey, I used the rainex anti fog chemical. Worked like a charm
