Welcome to Stovebolt.com
I have have never seen a reproduction. Place a Parts Wanted ad in the Swap Meet and regularly check the Parts For Sale ads in the Swap Meet. These Suburban parts come up every so often, but you have to be fast to respond.
What I do not like is that sellers are allowed to post a price and "OBO", meaning they wait to see who makes the best offer above the stated price. This makes the Swap Meet more like a silent auction - not my rules (I am just stating what I was told when I complained about it). And, in the end, it did not matter - I got burned by that seller, who sent the wrong parts and then disappeared. Let the Buyer Beware. If you buy from a person who has made a lot of recent posts, you will be safe. A regular poster/seller will most likely not burn you.
