    Another project...

    I was looking back at posts about the roof rails.
    Cutting them loose, sanding the rust and coating them but
    putting them back...Would this work?
    Just a zip screw instead of welding?

    How much side to side motion do these support/prevent?
    As long as there wasnt much weight on the roof could they be eliminated?

    Screws would work. I attached my dog house with good rivets. Either way any fastener used correctly will be fine. The factory builds using welding because of cost and efficiency on the line.

    I would recommend also using that auto-body caulking to bond the metal. Makes a huge difference in tightening up the vehicle and preventing any fasteners from loosening up. It dosnt have to be "body adhesive", just about any cheap paintable caulking will do but stay away from anything with silicone for this job or you will have painting issues.

    What do you do to minimize squeaking in the long run?

    I screwed the doghouse down with sheet metal screws. I insulated the doghouse. With the sound of the 350 under the doghouse of my 66, I never noticed any squeaks. I just heard the rumble of the engine.

    Yup..a very squeaky toy...that gets amplified by the tin can shape of the van.

    The roof supports do more then just support the roof, they add rigidity to the while body.

    If you want to minimize fab work, use blind cherry max rivets. Observe proper pitch and edge distance ( typically 1.5 times rivet diameter ) which over a disrance of 3-4 inches would work out to about 6 or so rivits and use good adhesive to rebond the support back to the roof.

    Self tapping screws might last for a few weeks or a few years depending on how you use your van.

    However it looks like it might be easier to weld up the joint..5 mins with a good mig vs drilling and installing fasteners.

    I know nothing about welding, but based on what I saw of how these vans are put together when doing a stop gap fix on all the roof rot of my 108, I would say Leroy is spot on. The one time I did any welding was on my old boat trailer with the help of a friend who was a welder. After welding some pieces together he said "now the two pieces are one piece of metal". That always stuck with me. It seems like those roof supports do more to keep the sides of the van together than hold up the roof sheet metal.

    I had bought the seam sealer awhile ago to seal the roof rails BUT.
    Putting aside that now I have to find the "3M Professional Caulking Gun"...

    The cartridge has a warning about using it in the interior areas.

    Anyone have any odor/fume issues after using the 3M 08505 Fast'n Firm Beige seam sealer?
