I am trying to come up with a way to eliminate the tin canning effect on my '73. Has anybody found a way to add additional support to the top? I am going to add insulation before replacing the headliner but I would like to some additional support to the top itself.

Any ideas would be appreciated.

I used a floor jack & a 2by4 to press the supports back into shape. (along the edges & along the beefier center part) I went high enough to actually distort the roof a bit, but it came right back into shape once pressure was released. I then put thin material between roof & support to prevent rattle.

One rig, I tac-welded a flat-steel "extra support" to the roof support.

whats this tin-can effect u guys are talking about??

The tin-can effect, for lack of a better name, is the hollow sound the comes from the top/roof that you may hear when you close your door. Sometimes you may hear a tin-ish sounding pop when you accelerate to around 50mph.

The problem is that the top only has one stiffening support member so the rest of the top has some flex that can make this sound. I want to add another support member about have way between the existing one and the rear before adding insulation.

Why not bend up some 4" 3/16" strips of metal and cram them in for additional support? Maybe glue them to the top to get rid of the flutter effect.

You can also get sound deadening panels. They work great to deaden metal noises. I use them all over my truck; inside dooe panels , on floor boards, inside quarter panels, etc. They come in various sizes and self adhesive to the metal. Also the 1" thick foam sound proofing works great. I believe I got them from JCW but other places have them also.

Good luck,

I glued some 3/4 inch styrofome and then quilted my head liner before putting it back in. That seems to work real well. And it is cheap.

They are only about 1/8 inch and stick directly to whatever surface. I have them on the front floor where your feet go, on the inside of the door stuck to the outside skin (doesn't have to be completely covered to deaden the vibrations), on my rear wheel wells, on the floor board infront of the passenger seat. They can also be stuck to the roof panels and covered with a liner. They are almost like a soft piece of tile. they can also be put on the quarter panel skin, I used the thicker nonporus 1" thick foil lined pads inside my quarter panels.

How did you put them in your panels?? u just stuck em under your panelsor did u enclose your panels somehow....that would seem like it wouldn't be too good for mudding.

If you go to a body shop supply house, they make some stuff called dum dum. Its a thick caulking that can be used in between braces and the roof and will semi harden. I also have some friends that are contractors and I got some duct liner and glued it to the roof. I then put in the headliner. This not only quieted it down but helps with the heat.

Never tried it before but I was thinking a good coat of Rhinoliner would do the trick. It should look pretty good too.
