Tony,
- Being in the commercial door business I buy fire-rated wired glass almost daily so when my Speedy glass guy was on the phone this morning I had him type in your 1/4 window application. . His system showed '69 2 Dr. Sdn. RH 1/4 glass still listed at about $60 but unsure of availability...he's checking on the LH situation, I'll follow up if it's a yes. .
Not that it would matter in your situation but I wonder what brand and date codes would be on something like this? .
