Hehr Standard Backframe Gasket Installation for '58

[mello mike]

I've got four Hehr windows that require new backframe gaskets. Some recommend using Olympic Rivets to install this gasket but was wondering if regular pop rivets of sufficient length would be suitable. The gasket does not mount in the trailer skin, but on a raised L-frame of sorts, so there is no risk of leaks. VTS directions also state to use just adhesive, no mention of rivets.

I'm interested in your thoughts and opinions on installating this gasket and curious how this installation went for others.

Mike, my ’55 Overlander has 8 windows and one rear storage door which all have the same backframe gaskets. All of my windows were pop-riveted in place at the factory. I’m replacing them the way I found them. Can’t see how a better rivet would keep it from leaking considering how much gasket there is on both sides of the frame. Not to mention the fact that I’m rubbing a small amount of RTV silicone on each rivet before inserting them.

That's very interesting, Spike. They used POP rivets for all of those? Hmmm.

Mine were all buck riveted which is why I chose to go with Olympics on the first window I did. But it did seem like overkill with the gasket and vulkem I used. Looks like I'll use POP rivets for the remaining 3 windows and baggage compartment.

I used pop rivets on most of mine also Mike. It was hard to keep the gasket in place while inserting the rivets so I applied clear silicone to the back of the window then clamped the window and gasket back in place on the trailer until the silicone dried and then riveted. this kept the gaskets a little straighter.

Doug,
I know what you mean by the gasket moving around. Next time I'm going to glue the gasket to the backframe using black gasket adhesive. After this sets up I'll apply a bead of black silicone (Trempro 644) to the back of the gasket then rivet the gasket and frame to the body.
