Not to steal this thread away from the loader discussion, but Sonny if you can't find a 2-1/4"spring hanger(I see your plight-'cause I looked for 'em too)-why cant you use a 3"wide hanger and make washers for each side of the spring eye to take up the difference in width of spring? the washers on each side of the spring would center the spring in the hanger..or so Im thinking?
the 3"wide ones for the F350 are all over eBay as replacement parts..have you tried (https://parts.ford.com) and entered in your VIN number they have a LOT of replacement suspension parts for Ford trucks
