They are from Robinson racing products, I can't rember for the life of me how it was they are made but a few people at our old track used them on there CW, Rayborn,nd Cobra cars I think the where great but also a copy on Assiocatied parts.
I don't think Robinson makes them anymore. I didn't see them on their website. I'm looking for a replacement part. Would the custom works steering block and c- carrier work? I think the custom works block doesn't have any angle in the block. Thanks for the help!
