The round button door handles on my '66 sunroof bug were worn to the point that they would not lock or unlock and barely open. I ordered replacement handles from The Real Source. They had square buttons but the workings looked identical to the original round buttons.
I still cannot get the passenger door to lock or unlock with a key, though it does open fairly smoothly.. The driver's side locks but locking/unlocking isn't smooth. I have to twist the key a certain way to get it to connect. It apprears that the tabs that the door handle paddle hits are pretty worn.
Do I have to find the inner workings of another '66 donor car or is there a way to retrofit another year's lock mechanism into a '66 door?
Or is there some other alternative I haven't considered? Thanks for your input.
