There's got to be somebody that's replaced the trim around their windows..... Frame and firewall are painted. Now finish painting the a arms and start putting it back together.
Check with a glass shop. They probably have access to rubber seals that we would never find. Another option....make a sedan delivery out of it. I saw a Falcon wagon a while back that the rear side windows had been filled in and it looked great.
Just went on the Metro site and found some for 1980 Malibu wagons http://www.metrommp.com/metrocart/detail.cfm?ModelNumber=LM 16-S/W&VehicleYear=1980&Make=PONTIAC&Model=GRAND LEMANS http://metrommp.com/ Hit the Online Catalog, click the year and check out Grand LeMans. Chevy Malibu wagons share with other models.
Both good options. I've got a couple of friends that own Triad Glass. They didn't know of anything that would work. Would like to keep the windows if at all possible. I'll keep looking. Thanks Rod
