Does anyone know where to locate replacement fender mouldings and steel wheel beauty rings for a '77 Concourse (Nova)?

The trim rings should be the standard 14 inch trim rings which could be purchased at just about any muscle car vendor (Paddock, Year ONe etc.) As for the trim pieces, they will be a bit harder to find. The first place believe it or not, is to ask your local Chevy dealer. It all depends if you have a cooperative parts man that has an interest in the hobby. Some dealers don't want to mess with it but some parts are still on the files if you look hard enough, eventhough they have been discontinued. Your second place is Ebay motors or National Nostalgic NOva in York Pa. The Chevy2 reference in the previous reply is another Nova source. Lastly, is a junkyard source. There are many salvage yards which have parts available for '70's cars. You see, the problem is we don't have a lot of reproduction parts for GM cars past '72. There is not a big demand for it. Does the fender well molding fit '75-79 for all concours, LN, SS, and Custom and Rallye Novas don't they? Hope this helps,
