Yes I've ordered from there before many times. I'd call 1st to see if in stock, that way there's no back order or refund issues. Duanes the dude to talk to. He's the owner and not a ripoff in any way.
I only found one eBay seller with that, and they want $100 shipped for it.
Dax has it for $49 + $9 shipping if it's in stock.
It's an interesting kit.
I wonder how well those welds hold up?
