1968 GMC C15 clutch bellcrank assembly

[pcunningham]

I am desperately seeking a bellcrank (Z-bar) for my 1968 GMC C15 with a SBC 350 (casting number 638) with a Tremec TKO600 5-speed. I've looked just about everywhere but everything I found seems to be for Camaro's or Nova's. Classic Industries sent me one (part #17113) but there is no way it will work. I need the complete assembly to include the pivot ball to the frame mounting hardware. Can anyone point me in the right direction with finding one of these for my truck?

Thank you for your assistance.
