'63 Valiant V200 wagon - rare bolt issue

If I do a self-tapper, I need 7/32, not 7/16.
yes sir I get it. The bolts in your post you said are 7/16 20. Then you posted a hydraulic system banjo bolt with that same thread. I was just trying to help you get a replacement bolt for your original damaged bolt. Not a sheet metal screw. Typically these pieces do have spot welded nuts or some sort threaded body fastener. The nuts can usually be tapped but the clips or fasteners not so much. An any event if the original bolt you posted is a 7/16 20 they can be bought. PEACE OUT good luck with your project.
