I am using the reproduction of the factory type arm with the clevis pin connection to the bell crank (z-bar) as some corvette arms use. It fits the Lakewood scatter shield well and attaches to the factory mechaical linkage. It comes straight out horizontally but has a few bends going forward. From the front or rear it would appear straight. 454/M-20 and 11" hays 3-finger clutch.
