K member question

From 67 to 72, there are at least 3, V-8 Ks; 318,340 and BB; the 340 K being a modded 318 ( modded at the LCA pin mounts) with the aforementioned welded on washer for IDing it. The basic Ks were all the same, with the differences mostly being the engine mounts. The 67 was a little different in that it had a single shear idler arm mount .I have at least one of each.
