I had a hard time finding any feedback as to where to place these and one evening, just decided to take the plunge and pop them in where I think they need to go. As it turned out, very coincidentally, the holes I drilled was nearly identical to where they were supposed to go as they had been bondo filled before the paint job.
The larger of the gumdrop bumpers goes into the upper right corner of the driver door opening, about 1" to the left and 1" down, thats where the hole needs to be. Just the opposite on the passenger side.
The smaller gumdrop bumper goes into the bottom left corner of the drivers door. There's a flat area there and the bumper goes in about 3/4" from the left edge to the right and about 1-3/4" up from the bottom edge.
The flat round disk like bumper goes into the door edge just opposite the vent window about half way down.
I installed all three bumpers into each door - WOW! what a difference that made!!
I'll get some photos of where they ended up and send them out at some point, maybe it will help others in the same predicament.
