Mornin All:
Beautiful day in Tennessee, all the MG's are in Gatlinburg and I'm working on my TR. Yea!
Question though, when I bought the TR it was mostly apart, basket case as they say. The carpet and underfelt were long gone. I have a new carpet set and new felt and I am wondering if the felt goes only under the floor board carpet or does it go under the tunnel carpet also?
Any thoughts would be greatly appreciated.

Cheers, Tinkerman
 
I think both, but I'd definitely get a second opinion. I know putting some modern heat/sound insulation down is a popular upgrade. Won't impact the look once the carpet is installed but it can help quite a bit with noise and heat.
 
On my 59-TR3A felt was supplied by Moss for the floor areas only. After driving it that way for six summers I pulled all the carpeting out again and installed 3/8ths heat shielding on the floor, tunnel, and firewall (NAPA). I then put the felt and carpeting over that. The heat shield helps but after another three summers I should have installed air conditioning. Just kidding about the air but we do try and drive in the morning or early evening only on the hot days.

I agree. Put it under the tunnel. Also a little easier on the elbow it you rest it there. A little note. Should you do carpeting again sometime. Go to an upholstery shop and buy the padding in bulk. Trace your carpet pieces out on the padding with chalk and move it in 1 inch from the edge.
Much cheaper and very easy to do.
 
My TR3A came with two pieces of undercarpet felt glued to the top of the tunnel. One is about 8 inches in diameter and surrounds the gear-stick hole. The other is as the photo attached. Note that my TR3A is an early one with the top fill hole and dip-stick. The original pieces were removed and replaced when I did my restoration from 1987 to 1990.

As I was just doing this last weekend, I thought I'd throw in my comments. I replaced my original (funky, faded, grotty) front carpeting w/ a NOS 70's era 4-piece AMCO kit; very poor fitting, but a cosmetic improvement.
My old original carpet was glued to the driveline tunnel; no padding there for me. On top if the removable gearbox cover was an 11"X17" pad. I replaced my old insulation under the seat carpet with some stuff I scrounged up from a carpet store near me; it seemed new enough. I wound up reusing the old carpet under the seats, but the new padding there was thicker than the old, making it harder to move the seat forward and back.
I'm interested in the various thin, heat-reflecting modern insulations like Dynamat™, but am worried if rust can start under there. Have fun!
 
Kevin - if the floor pans have POR-15 or similar on them I don't think Dynamat would be an issue. Anyone else with experience here to add?
 
I'd stay away from anything that can absorb & hold moisture. Go to Home depot or Lowes & look for HVAC Aluminum foil type insulation, comes in a roll & a lot cheaper than dynomat.
 
I have self adhesive Dynamat asphalt-type pieces cut for my front floors. But I haven't installed them because I'm worried that any water could seep under them and get trapped between the Dynamat and the floor panels.

I have a roll of the foil type that I'll probaby use instead since it's removeable. Plus the asphalt mat would probably get soft from the exhaust heat and be hard to remove later.
 
Thanks all of you for your input on the under carpet felt. I now have a direction to go and more importantly the person who is to install the carpet will know also. You know as I read all of the posts It dawns on me that maybe I can do the job myself! I'm a pretty good wrench so I might try it. It would be fun to work with clean stuff for a change!

I got home a week ago from TRA. I drove the TR3A a total of 2200 miles. On the way from Buffalo to Montreal, it rained for about an hour and a half. I hate putting the top up so I carried on in the rain. Near Watertown, NY, hail the size of grains of salt were impacting on the back of my left hand. When I arrived home, I took out the seats, carpets and underfelt and let it all dry. The floors are still clean and rust-free like they were 89,000 miles ago when I finished my restoration in 1990.
