So I had this 67 slant sux K frame. Awhile back I built a jig to convert it to V8, and I also lopped off that 1 year only bastard child idler arm mount. The improved mount is from 68-76. So I finally got around to making a jig off a 68-76 A body K frame to locate the 68 up mount i do have exactly. Now I can bolt it up tight and weld it in without any fear of geometry issues. I may only use it one time, but at least I have it in case I convert another K frame or need to check for straightness. Heres pix.
