    So I purchased a factory roof rack from a junk yard near me. They told me it has all of the mounting hardware and to me it seems like it does.

    I have two questions:

    Where is the proper mounting location?

    How is it attached to the roof? Do the screws go right through the roof or are they screwed into threaded inserts?

    Any pics or info would help.

    Thanks.

    Heres where I mocked mine up after looking around online a bit.

    There was a thread about this recently, it seems that they were installed in slightly different locations. That one looks like the '89-'91 style. Mine is the older style, but the mounting screws are machine thread and thread into nutserts in the roof skin.

    I was going to say, I don’t have any hands on experience with a roof rack but I would think that they would have used nutserts.

    The one removed from my 88 were sheet metal screws and did not use nut serts. Around 14" from rear I believe was general install.

    Back in the day...Jesus that makes me sound old...
    Anyway when I ordered my new Sub back in 88 I made sure it had a roof rack. It was actually a dealer installed option and mine was just installed with sheet metal screws.

    When getting parts from that yard I usually walk the yard and pick stuff out but this time I had them pull it for me so I didnt see how the roof skin was after removal. They did give me a bunch of sheet metal screws which is what led me to believe it goes right into the metal without a nutsert. The rack came off of an 88 GMC Suburban 1500.

    I'm leaning towards laying down some painters tape, drilling pilot holes and screwin it.

    It should have came with a set of rubber gaskets that can be used as templetes.

    Yes, I have 8 gaskets. 4 large for the forward and rear most mounting points and 4 smaller ones for the center mounting points. They are hard plastic though, not rubber. Should I get some some sort of thin weatherstrip foam in addition or is that all you have on yours?

    That was all that I have. To be safe can put a day of sealant around the holes before putting the gaskets down.
