1963 Rear Heat Shield Thickness

[Harry S.]

Any 63 owners know the thickness of the metal on the rear heat shields. These are the two in the back that cover the exhaust tips close to the muffler.

I've had a set for at least 15 years that is .078 to .093. I acquired them prior to LIC making them as I recall. The LIC set is half the thickness.

Harry,

If you are talking about the shields that have a flange about 3/8" +/-, and a slit in the bottom, mine are right at 0.040"

These are off a car I bought in the 80's as a basket case. It had been apart for quite a few years before I bought it. so, my guess would be they are original.

I can post a picture later if there is a question.

Monte, thank you. No need for a picture.

Re: 1963 Rear Heat Shield Thickness

Harry, I thought the important dimension is the ID of the heat shield, they slip over the tips and that's where they are hard to install. Are you having trouble with the thicker shields?

Tim, I'm trying to determine what the original metal thickness was. The LIC set installs very easily. This thicker set that I have is difficult to install but it does go on. I'm just wondering if the thicker set is NOS or some old attempt to reproduce them.

Thanks

Re: 1963 Rear Heat Shield Thickness

Harry, I have a repro set from either CC or Paragon but what seems important in installation is the thickness of the tail pipes as they install over those. The tail pipes I have are thicker and you can just bearly force them on.

Re: 1963 Rear Heat Shield Thickness

I had a bear of a time putting them on over my aluminized pipes. They seemed to just go on so far and that's it, but the tips seated at just about the right position that I like under the bumper.

Re: 1963 Rear Heat Shield Thickness

Question: Are these heat shields designed to butt up against the rear exhaust panel? If so, my fitting isn't working well. However if they are supposed to butt up, the tailpipes don't go in far enough to be equal under the rear bumper.

Thanks

Absolutely correct, I've had to apprise several 63 owners to buy the "right" tailpipe extensions if they want to use the heat shields.
LICS used to have a warning on their product list about this; don't know if they still do.

Re: 1963 Rear Heat Shield Thickness

Any chance someone can share a picture of the correct positioning of these shields?

Go to 10:17 minutes and watch until 10:42 minutes into this video:

Re: 1963 Rear Heat Shield Thickness

Frank,

It looks like these butt up against the back panel and the exhaust tips stick out just below the bumper. I can't get the tips in that far and yet keep the shields up close to the back panel. I wonder if the heat shields can be expanded a bit to make it easier for the tips to go under the shields. Maybe a muffler shop can expand them a bit??

Thanks for sharing the video.

The exhaust tips extend out almost exactly 5-1/2" measured from the bottom of the rear valance chrome tailpipe bezel to the bottom of the end of the tailpipe extension (also shown and discussed in the video). So that's a good benchmark to position those..

With the proper "correct" thickness extensions the heat shields should not need to be expanded. Make doubly sure you don't have the overly thick Chiwanese tailpipe extensions. LICS used to sell the bad ones as well as the correct versions.

I can't say for certain if a muffler shop could expand the heat shields - but I think so.

I have an NOS set or exhaust tips and the thickness is shown in the picture - IIRC the thin ones are 0.030" and the thick ones are 0.044". About 50% thicker, Original exhaust shields will NOT fit over the thicker extensions (ask me how I know).

Re: 1963 Rear Heat Shield Thickness

Thanks. I'll measure mine and see where I go

Re: 1963 Rear Heat Shield Thickness

Just measured a set of extensions I'm restoring. Inside Diameter is 1.92 inches, thickness 1/32 - 3/64 ( a little bent )

Also measured an NOS rear heat shield, Inside Diameter 2.05 inches, thickness .0300 - .0320
