The 67 idler arm is more expensive than the 68 or 69 but I think people are making more out of it than need be. I have both k frames in my two cars. One has a 67 k frame and one has a 68 k frame. I don't know how inferior the 67 k frame is but I drive my GTS dart pretty hard and not in just a straight line and never had a problem. The difference in price between the 67 idler arm and others is like $120.00 vs $80.00. You are able to purchase a replacement through many of the suspension companies like PST for example. I personally don't think its a good idea to modify many of the 67 k frames to change over to the 68 style. Many people may want an original k frame in their real factory 67 bb a body. Is there really that much of a problem with the 67 idler arm setup?
