I searched and it looks like a lost cause, but anyone got one for sale or know where I can get one?

 

they come with the kit.

 

You can post a "WTB" ad in the Black Market. Make sure you read the rules to the Black Market before posting a thread.

Try contacting RJ directly, I don't think he sells it separately but I could be wrong. Additionally, try, craigslist, ebay....or look in the Black Market.

Good luck.
