If you are referring to Koffels B-1 Shaft Rockers? I have a set that I will sell. I went to T&D Years ago. I broke a shaft,, well the stud backed out and broke the shaft.. Never replaced the 1 shaft, but everything is still there... Also Scott still sells them..

Just curious, but what kind of work is needed to go with the paired system? and how about the Spray bar system??

Thanks,
