This is very good interesting info. I like the discovery from the same product compared to a sibling.
The attached photo show one stock inner door latch handle. Till this day I could not/can not find some one to mold cast it out of aluminum or magnesium. The gridlock has me vexed and I will fabricate something to work/look like the original eventually, but time has been fleeting lately.
MoparJ, like you said, I have on occasion also felt a slight hair difference in the same parts since my feel at hand can detect the slightest weight differences after all of this madness.
It's especially fun when it comes free of charge.
