make your own!!! nothing but 1/2" plate. Make a template and have someone cut them out for you if you don't have a torch or plasma cutter. It's a step or two below rocket science.
I am more than two steps away from rocket science. I can make them, but have other parts of the car I would rather work on.There is a laser cutter here localy, but for small quanity orders, you go to the end of the line. Might spring the 50 bucks and order some.
I wonder how many sets that guy has sold. Mine start off at $18.00 http://www.industrialch***isinc.com/?product=1935-36-rear-wishbone-mounts
