Re: clifford and efi exhaust

Use exhaust manifold clips and studs as shown by Frenchtown Flyer and others to keep the efi exhaust manifolds from drifting out from under said washers on the carb head.
I really struggled till I got the clips on. Mine went right on with the alternator bracket modification as explained earlier.
