Mine had it as well!!!!

What should I replace it with ? It's kind of hard like a clay , should I remove it and cover both humps with insulation / dynamat or a fiber pad . I havent fitted the rear carpet section yet ,but if it is supposed to be there then i'm going to guess that the carpet manufacturers take it into consideration ,and i'm going to need to fill up the space ..
Thanks guys

there,

Sometimes I can be really DENSE!!

I am having trouble visualizing what you are describing, "kind of hard like a clay" type substance over the top of one rear wheel well...

I've done 3 carpets, one in my own 81 and 2 in other friends 1981's and I do not remember anything under the original carpet except the 1/2" or so insulation/sound elimination material directly under this material was the fiberglass floor board or inner fender.

Look up under the wheel well of the one that has the clay like substance on the inside, you might find that was a repair of some kind

Just when I think I know about everything there is to know about our 1981's I learn something new

I used the aluminum two sided bubble insulation I bought at Lowes did the entire floor before installing the new carpets

Good luck and from experience, I KNOW your 1981 just love's all this attention and quality time you two are spending together :dance

I put in some carpet underlayment (insulation) about 1 inch thickness.

Is this what you used? Bud

I'm thinking about doing carpet in mine. I know it's not a C3 but If it's good enough for you it should work just fine in mine.

You still have the ZR1 running I admire your stamina and mechanical ability that BLACK ROCKET should be very glad it landed in your capable hands

Yep that be the stuff

It dawned my why you have a BLACK ZR1 weren't those Polaris air bubbles all BLACK too

Took a quick picture of the well ...no damage under it and it looks kinda factory ...any ideas??

I can neither confirm nor deny.
Thanks for the complements

I don't know what that would be...

I know what I would do

I would leave the "kind of hard like a clay" stuff there and when you have your carpet ready I would lay it in over the entire back end and see how it fit. Then try it with the new insulation, if it looked good, then

If it don't I'd cross that bridge if it seemed not right

Same as mine on both sides. God only knows what that is but brittle as hell and tends to crack on the edges (had to tape mine). Reflectix sounds like a good substitute.

I think the clay like stuff is the original sound deadener. My 82 had the same on the passenger side. The driver side had a thick black tar paper like covering that I would also guess was original. No idea why they would be different but I left them that way.

My replacement carpet fit pretty loose over the the wheel wells. I added padding on top of the sound deadener in select areas to get the carpet to lay in a smooth arc over the wheel. For padding I bought Mid America's box of sound deadener. This is an inexpensive box stuffed full of various sized pieces of foil-backed padding.

I put a dynamat like thin rubber pad on the floor of the cargo area and up the back wall. I then topped the floor off with another piece of foil-back padding from the box. I also used the rubber and foil-back combo on the floor pans and trans tunnel. This makes a big difference in cabin noise and heat.

Whew , at least I'm not alone , so it probably was factory , guess I will seal it up and work around it with new insulation ..
Thanks to all ...

Purchase the assembly instruction manual (AIM). The AIM has five or six pages dealing with the installation of the factory sound deadener. In a nutshell, it was sprayed pretty much everywhere, inside and out.

The AIM also shows installation of the carpets.
