looking for 5.7 to /6 k mounts....

I would NOT use a 67 K. I own a 67 currently with the factory 67 V8 K. Because of the "one year" steering linkage, (idler arm is 200 bucks) I'm going to swap in a later K when I get around to the disk brake swap. This will give me a late V8 K, disk brakes, late steering link, the whole deal.

These setups are just not that hard to find. I got mine in an absolute horror of a rusto junk Demon for 300 bucks
