Door Glass, Whats the difference? Advice sought. Options

[frostyf]

Given that doors got a reinforcement bar (late 73?) And the winder mechanism swapped from cable to scissor, does anyone know if the glass wind up window dimensions are actually different?

If you bought decent glass from a 1970 car, would it fit a later type door? Can you swap older glass onto a later door or are they completely different.

Grateful for any advice from those who know!!

At about 1000 cars into 1973 model year the doors and most of the parts for the windows changed. The window lift system went from a cable drive to a scissor lift system. Then as of Jan 1, 1973 the doors, at least for the North American market, also received the crash protection beam inside the door.
You can try swapping entire doors, but switching parts is not something I would consider trying.

^ Thank you. That info fits with what I know, though I suspect nailing the actual changeover date down might be tough. My guess is using up parts was a priority.

Conversions have been done, but what I saw prompted me go find a pair of late doors. Then I found an NOS early top and got cold feet. Back to early windows I went. One early > late conversion, mostly cut/bolted in: http://www.914world.com/bbs2/index.php?showtopic=322769

Paul Sayegh did a late window/early door conversion in his black 914 3.6, but I can't find pics. Like everything else on that car, it was done really well.

"digging into hell" classic thread also shows the conversion to late mech into an early door.
