Need a little help finding some marker lights for a 1982 Shoreline trailer. Need the amber marker light assemblies. I've found where I can buy the replacement lenses but I need one assembly so I might as well replace both. Part number on lens is Acutek 201A, cross references to Wesbar 3141A and also has a part number of 42-3008. I've found all this info but can't find anywhere to buy online since it's a discontinued part. Thanks for any help!
