Couldn't wait. I ended up welding them in. There was a cheater weld ring from the factory where they used a buttweld on the pipes and the fishtails when they built them. I filed the ring until the baffle fit inside, tapped it in about half way on the ring, hit it with a couple spot welds, and done. They will never come which may not be a good thing, but oh well. Its done and there is no damage to the chrome.
The extensions are on, the fishtails are mounted, and aligned. I'll fire it up tomorrow after the hi temp has a chance to cure and I triple check I wiped everything down completely. It's probably still loud...
In hind sight, I think it would have been better to buy some fishtail end caps and weld them to a pipe of the correct length then chrome the whole thing. As it turned out, the extension seam is not visible, so I got lucky.
I'll post pics tomorrow, barring rain all day.
