Left and right door handles the same??

[postman70]

Hello, I'm wondering if anyone can explain to me about front door handles and lock assemblies. What is the difference between the handles on both sides? I notice each handle has 2 part numbers on it. It appears that if you mount the handle on one side of car the L is facing up and if you mount on other side the R is facing up. Also it appears that the shape of the lock cylinders are different on each side where the thingies with the L and R on them mount to. My question is if I'm installing the drivers side door handle Should the L be facing up or down? Which side gets the square shaped lock cylinder and which one gets The other shaped one? I guess the other shape could be considered rectangular? Idk.. what happened is I took both my locks out of original door handles and looked through a few sets of handles I had and than put the locks back in the best set I could find not minding which side is which

The different shaped key holes are handles from different years. The same key would not work in both of them.
