Rubber Door Bumpers

How many bumpers are installed on each door? My truck has three holes. My truck's pre-disassembly photos show the top and middle holes having the bumpers installed. The photos don't include the area that has the very lower hole so I cant be sure if it was installed. LMC shows two bumpers, at the middle and lower holes.

Any ideas?

Both my 1970 Blazer and 1972 Cheyenne had those bumpers at the top and bottom location only. Nothing in the middle.

Re: Rubber Door Bumpers

Interesting... All the 69 and up trucks above show the top and bottom locations with bumpers but no middle hole.

1970cstblazer, I also assume your trucks had no middle holes?

Wonder if it's a 68 and maybe a 67 thing?

If have to check my stash of the removed parts to see if there a total of six bumpers. I'll probably use all six holes.

Thanks guys. Anymore input?

Re: Rubber Door Bumpers

My 67 has the three holes but I find that the rubber in the middle rubber keeps getting broken. maybe its just my fat butt catching it.

Re: Rubber Door Bumpers

My '68 has the top and middle bumpers, but there is no hole in the rocker panel for a bottom bumper. I believe the rocker panels are original.

Re: Rubber Door Bumpers

I just thought of something. The rockers on mine are repros. I would image my original bumpers broke upon removal as I don't have them in my stash and no photos of that area.

I'm going to assume it didn't have the lower bumper. I can't see a pattern as what years had what...
