Does anyone reproduce factory style K members ???

What is it you are looking for? What do you have at the moment? I have repaired a few k-members that had some real issues including one being WAY out of square. Others have converted slant k-members into V8 k-members. We had a guy here who has made a jig to replace the '67 idler arm mount with a '68-up.
This deserves a 1000th like.
