If you have a 67 K frame, you have these choices:
1.....Use the 67, K, find a rare 67 idler, and then find compatible pieces, the pitman, box, and center link
2......Use the 67 K modify the K to accept the better/ more common idler arm and your choices just got better
(There was a recent thread re: a jig to mod 67 K frame idler mount)
3......Find a 68--72 or 73/ later K and go from there. 73/ later uses the spool motor mounts
