I think I've got what you're looking for. 4 Yakima Control towers with landing pads and hardware. How about $90 plus shipping? Does that work? Feet are in good shape. I can send a picture if you like.
Bill,
Thanks for the offer. I just did some digging around and I found the bases that I actually need for a Thule Setup so I am going to look for just the Thule 430 setup with 50" bars now.
