The interchange shows Olds Pont Buick with the same horn relay, at least in some years. After looking at a few cars on display, some must have been changed out. I think the one on my car is correct, but not working. Does any one have a new old stock #391924 for sale. I would appreciate a picture of it and price. Thank you.

 

Not sure of the part number, but this one interchanges with Buick models to 1966.

eBay for $50-$70.

 

That is the one I need, alright. Thanks. Now to find one NOS.
