So I found what appears to be a 300 degree din gauge pod for sale for a couple dollars. I'm not sure if its real and don't remember if any other companies made something similar. Is there anything about it that would tell me its a 300 degree? The back of it looked kinda melted or something. Not sure if thats how its supposed to be or if it was glued/modded. Can someone post pics of the back side of it and any other detailed up close pics? Thank you.
