I have a few pieces of old glass with defroster lines and when some friends started asking me to buy my clear pieces, I tried to scrape the defroster lines off with a razor blade. No work!

Yet try to peel off old window tint film and the grid peels off with it, leaving only the etching...

You might be able to remove the etching with a slurry of tin oxide and a lambswool buff. We use TO to remove scratches from gemstones, haven't tried glass, but works on quartz.

Sanity Check?

The original rear deck lid glass was "clear" with no "defroster lines". - Right? Clear meaning no tint ??

If the objective is to keep the car faithful to "original" - then you need a clear glass with no defroster lines. Keep in eye on E-Bay, visit other Z Car sites and post "Wanted Ad.'s" etc etc - then pay what you have too.

If you get a rear glass with defroster lines - then remove them.... aren't you still looking at "tinted glass" instead of clear? That buys you nothing in term of keeping "original"...

If you are going to tint it anyway - it won't be faithful to "original" anyway... right? So what's the issue? Get a new rear glass - it will be tinted with defroster lines - then add window tinting film as dark as the lines...

Hook up the Defroster - per the Factory TSB... and you'll have a car as delivered from a dealer - that might have preformed the job... now is that "original" or not? I don't know if following the Factory TSB's where modifications are directed - is considered "original" or not?? how it would be judged?? - But then you don't care about that anyway if your going to add tinting film.

I have a good glass and hatch from a 74, its yours if you want it.

Carl, point taken, either go original or do what works best for me. Guess I will look at replacing the glass and hookup the defrost, though not much need in AZ!
