In my 69 Firebird (with deluxe interior) the door lock knobs are different on the left and the right hand sides. One has a sharper edge in the top (like a funnel) whereas the other has a more rounded shape. Both are chrome though, and have a smooth stem.
When I look in the vendor catalogs, I find conflicting information. The one with the sharper top edge seems to be for 1967 and older GM cars. For 1968 up I find two different knobs listed, one with a ribbed stem and one with a smooth stem. Both of them has the rounded top.
Does anyone know what the correct door lock knobs for a 69 should look like?
