Marcos Maniacs

Well Dwayne, all I know is that when I was talking to Gem Marsh when the
straight 6 Volvo version first came out he told me that they had to get
glass rear screens  to comply with US regulations.

Maybe they only had one batch made and after the first car passed whatever
test was needed; then when they ran out of glass ones they went back to the
plastic ones which must have been a lot cheaper.

The regs were different back then. Mine is a 70 3 ltr Volvo LHD originally a

USA imported into the state of NY before being exported to Edmonton AB,
Canada 
and it had the original plexiglass rear screen. When I last replaced it many

years ago when Marcos was still alive, the replacement from Marcos was a 
plexiglass unit. The front replacement screen was a Heated laminated glass 
windshield.

Dwayne
