Believe it or not, I found close Wright matches on eBay! Not original part numbers, but closer than anything else I have found. They are numbered 3047 and 3050, but look identical in design to the others in my set. Made offer to seller, and he accepted! Replacements on their way as of today. This set is going in my Tundra as a working user set, so had to have something to fill the gaps until I find originals.
Would still like to find originals, if anyone digs any up in their odd socket stashes!!
