installing custom roof racks

If I wanted to install roof racks on a '65 - '68 Cadillac, what would be involved in making this possible? I'm sure it's the same type of process for any make and model, but I figured I'd be specific.

Do you just drill in roof racks? How would that work out?

Ideas/suggestions?

Thanks!

There are plenty of universal racks that clip onto the rain gutters. As far as mounting a bolt on one, the hard part would be finding one that fit the roof. VERY few sedans or coupes of any make had racks. They were usually found on wagons with a large flat roof. But if you did find one that was close enough you could put "riv-nuts" in the roof that the bolts would go into. For years GM used a rubber nut that works with no special tools. The hole is about 3/8" for a 1/4" bolt. You just drill the hole in the roof drop the nut down into the hole and place the rack on, put the bolts in place and tighten up.

They used them on the trunk racks on Vettes in the seventies and many other places as well.

Even if I can't find pre-made racks that fit the curvature of the roof, I can always fab something up. I don't think that would be the difficulty.

You say drill into the roof. That's what scares me a little bit. Just drill right through to the other side? Wouldn't that cause some sealing issues? Or would a threaded in both be enough to keep the elements out?

Like I said, the factory used those rubber "rivnut" like nuts for years. On most they do use a "blind" riv-nut that has a bottom on it. But those rubber ones seem to work. Just put a piece of tubing over your drill bit to limit the depth it goes in so you don't run a hole thru your head liner!!

Roof racks have been installed at the dealer for years this way when the customer wanted a roof rack but it didn't get put on at the factory. Most roof racks could only be bought in a kit form in fact.

So then the rivet wouldn't penetrate through the entire roofing, allowing no sealant issues?

That's my biggest concern.

The roof rack on my Blazer has the rubber grommets that the screws and bolts run into.like Martinsr says....... That seals it from the weather, even though there are holes in the roof.m There is also a rubber strip that they sit on that acts like a gasket.

My question to you, is WHY would you want to do this to a classic Caddy?

Why roof racks? For the sole purpose of surfboard travel/storage.

I think I might go with a weld with the roof racks. Reliable, and I'll definitely know I won't have problems with sealing.
