Getting aftermarket door handles to work and be reliable is difficult full stop.  Getting quality parts is the first step but even then like in this example the chromed brass door handles were exceptional quality but the mounting was pressed tin and very sub standard [crap].  So in this instance made up stainless steel bosses to mount in the door skin with a white metal bearing pushed in to take the weight and punishment a door handle has to endure. Then a bracket was made to support the whole assembly and then the sheet metal had to be modified to accomodate the geometry of it all. Part of a larger job of doing a complete door fit out with power windows and bear claw catches. Not for the faint hearted, a lot of patience and testing and modification is required. An art deco style edge was machined into the main stailess steel boss and then polished to a mirror finish.  Adjustment was provided for in the mount so the handles can be lined up and not look droopy.
