help - OEM roof rack install?
 

hi:

About to install an OEM roof rack on my 1989 suburban.

Headliner is out.

can anyone post pics of OEM roof racks (esp. including interior of roof) so I can see where the 4 "feet" (6, including the middle ones) of the roof rack were drilled and mounted?

There are no indentations or other indication (that I can see) of where the factory installed the roof rack.

Thanks for all photos/comments/advice!

I did install the rear vent thing. . holes were pre drilled.
