I have a set. They're beefy and do a good job of cleaning up the area under the spring pack. I picked them up after tearing off one of the shock mounts and saw that Joe at Darlington had reduced the price.
When I ordered mine, he was stopping production for a while because he was in the service. That was at least last year and I remember some of the east coast guys posting up that they had run into him and he was considering making them again.
I think it was Brent who spoke with him. Haven't seen him post in a while, maybe he'll chime in.
