I have one smog system that is non functional. I took out the inserts and put in a button head socket cap screw. One similar to this, but without markings on the head. Smog pipes seal nicely against these.

I used steel rod and welded a lip on it like the tubes had. Just slips in the hole where the tube was and the upper tube clamps it in place.

1/4" clevis pins fit perfectly in the tubes & it has a flange that will seat against the manifold. Pull those long tubes out of the manifold or the nut on the tube won't look correct. No welding is needed. I did this on my big block car at 83k. At 157k they looked just fine. Use a BB in the vacuum hose from the carb. to the deverter valve. I just mentioned all to Larry Christenson & that's what he said he would be doing. Really easy....Joe
