68 GTS 383 with PB & PS

If i would have had a Big Block GTS K-Frame it would have worked better.My slant six k-memeber ; the mount is in the center-close to the gear box.The GTS is all the way up front.

It really doesn't matter which k-member you have, what matters is the mounts. Since a slant could come with power steering the mount shouldn't hit (at least that's a theory). All of our big block builds have used home-built Direct Connection k-members which use 74-78 motor mounts. They are tight to the steering gear, but they do fit.
