Looking for 355 LH Driver wiper arm

Posted in wanted, but thought this might get more exposure. My original arm snapped at the pantograph stud. Found another mangled arm with a good pantograph end piece and grafted it to my broken arm.

Worked great for a few weeks, until I lifted the arm to wash the windshield and let it slip against the windshield........ugghh....immediately broke the stud......again..... do these break that easily?? .LOL
So....searching again..... I am looking for 64610300 for a 355.

Any report on whether the Hill Engineering replacement is less prone to breakage? If yes, I might be interested in another arm with a broken stud and buy the replacement
