68 GTS 383 with PB & PS

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.
74 thru 78.Didn,t these mount have a bolt that ran through the mounts? Instead of the nut up through the bottom on each side.I think i know what your talking about.
