Dorman has been in bussiness for decades,maybe longer than I've been alive!..sold a lot of their products at the stores I worked at,like brass fittings,hardware,and electrical items like bulb sockets,and lately they bought out Motormite,who made the "HELP" brand of hard to get,formerly "dealer only" items,and now they are expanding their lines quite a bit--I see they now sell P/S resivouirs,Upper and Lower A-frames,Harmonic Balancers,axle shafts,exhaust manifolds,driveshaft support bearings,all kinds of body moulding clips and specialty items and countless other parts you often cant get anywhere but a junkyard once a dealer decides to drop it from inventory..
Dorman WAS always high quality american built parts,but I cant say whether or not that holds true today,I wouldn't be surprised if a China factory is making a lot of the stuff they sell today,just like every other "name brand" company that now uses their NAME to sell parts,but unfortunately the quality they once had no longer is a gaurantee like it was years ago....still,it is nice a company like Dorman is making "obsolete" parts and hard to find items for us old vehicle lovers,otherwise we'd be pretty much boned when it comes to finding repaor parts...
