Those are called AN490 "rod ends", at least there's a steel version named that. AN490's can be bought from Wicks at http://www.wicksaircraft.com/catalog/product_search_results.php/search=YW40OTA , go to http://www.wicksaircraft.com and search for AN490. These are steel though, and are therefore a little on the heavy side. They are made to rivet or weld to 4130 tubing. I don't see any 1.25" in diameter, but there maybe be such a thing somewhere in aluminum. If Van's exactly what you have in mind, I'd think that would be the place to get them. Their prices seem pretty reasonable on the stuff I've seen.
