I have noticed people looking for Windshields for their older model Motorhomes. I was able to get a windshield for my 1989 model LaSalle by Champion from the following company:
Custom Glass Solutions by Guardian,
24145 W Martin Road,
Millbury, Ohio 43447,
They shipped it to Pembina, North Dakota where I picked it up. I was concerned about breakage but the way it was packed you could drive a tank over it and it would be okay (ha ha)). The surprising thing was that they had it in stock.They wanted the number off of the windshield which I couldn't read but being a 2 piece w.shield I gave them the number off the RH side and they worked from that.so if you require a windshield give these guys a try. \hope this info is helpflu. All the best for the Festive Season.
