no, it won't work at all without heavy modding. As you can see the passenger side runs head on into the A-arm rear mount.
It would take a sizeable amount of modding to clear.



The factory L84 (truck) manifolds are worse. The flanges span is about and inch too wide to fit inside the frame rails - so they are out.



I ordered a set of Hooker manifolds, part # BHS516. Hopefully they clear, another Summit customer noted they cleared his 72 Chevelle.
If not I will need to revisit modifying the headers.

I do not think they can work with the stock clutch Z-bar.
