What are the screws in the the wing window frame on blazers, or so i'm guessing, do? Is it just to brace the wing because there is no upper frame on the door, or is there some crazy explanation for what they do? They have an odd shaped black plastic cap on them. (sorry pictures wont cooperate)

Extra door / vent window support would be my guess :( , I saw those screws
on the other thread, mine do not have the plastic, they are flush in the door.

My Blazer is missing one. Is there a source for these?

Supposedly,outer skins were splitting under the wing vent.So,the Blazers gottem.The rest,not until,72.The funny thing is,I have never seen one split.

Thanks for the insight. I was getting tired of people asking me what they were for and having no clue.

A stock blazer door without the reinforcing inner to outer screw will flex a lot over time. There is a small strip of metal there that is supposed to hold things together but was not terribly effective. It's all kind of linked to the door hinges and the normal lack of lubricant. As the hinges stiffened, the doors would get all the stress from opening--it would appera on the door hinge plates and eventually to the inner and outer skin. I have a perfect example--will add a picture later~~~!

Man.....i've wondered why my doors have these holes in them that look factory. I'm definatley missing the screw head that covers it. all i see is a hole and a threaded shaft that is just sitting there.

Is there a picture somewhere of the nut I'm missing?

Are these what we are talking about?

:confused: that means the screws are broke off in my doors. I was picturing more of a nut looking thing.

Da, thought I've seen em all--this is a enw one one me. And just where does this go--under the vent window??

Did all blazers come with the plastic thing or did they come with just the screws in a metal sleeve like the trucks???
