I searched Virginia Classic Mustang and NPD and can't find the jute type matting that goes on top of the fuel tank on a 66 SJ FB. Any sources?
-
this it??

What insulation on 66 San Jose fastbacks are your referring to? Not a typically used/found item on these earlier cars
Goo subject though to discuss and to look at examples

Yes I see it on that car. Would want to see allot more examples with such a pad than a single example and from the same production period as the car being asked about. Looks like the OP was likely asking about a possible March built car. Would not add one to a 66 San Jose car based on what I've owned and seen but others may have different opinions.
Not sure what the blue liner is between the pad and the mat also but suggests someone has been changing or improving things
Will be interesting to see others as we discuss this future.

Thanks Jeff, I'm referring to what would go on top of the fuel tank (if any).
-
My first thought is that the gas tank looks painted which if so means a replacement. If the gas tank was replaced that calls into question if the pad had been added. I have not seen a 66 SJ car with a pad in a survivor context before which makes me question this one.
-
After reviewing the underside close up of the gas tank makes me more suspicious of gas tank replacement, Besides the duller look of silver paint on some replacement gas tanks the patina of the gas tank and shiny new appearing sender does not match its surroundings. Side to side the road grim covered exhaust and suspension and directly in front grimy leaking rear end center section do not seem to match the gas tank . This would not be a big surprise based on the other typical maintenance items that seem to have been replaced in other areas.

I have a low mileage unrestored March 23 '66 projected build Sprint Conv with black std interior from the Metuchen plant that I purchased from the original owner. The car has never been apart. It also has the same brown insulation on top of the fuel tank.

Thanks for sharing. Of course two owners or even dealers addressing a complaint from an owner could have come up with the same or similar product to add to a car back in the day. Given the large amount of 66's or 65 and 66's one might expect to have allot more examples found and seen over the years especially from one of the two most popular years and most often restored Mustangs since the clubs and shows started over 40 years ago.
The thread will provide a place to collect findings if more examples are out there and we'll have to be patient and see where it leads us.
21.04 may I as what interior the car you mentioned was ordered with? Looking for a condition or reason why the car might receive something different from others.

I suspect that jute mat is to cut the "sloshing" noise on cars such as convertible ( the well liner is a poor sound barrier ) and fast backs ( the door opens between the trunk and the passenger compartment) when the tank is partially filled. Coupes have the jute mat placed upright between the trunk and the passenger cabin. Maybe others will jump in on this and we will see if it is valid? So does your coupe have NO jute and does a convertible and fastback commonly get the pad? Lets see what others find!

Thought it might be connected like in later years with the deluxe interior but still have original examples in pictures and ones we've seen and owned without. Also could not find them shown in the assembly manual pages we have available. We'll see but one would expect that if it were installed through the year at all plants we would have seen hundreds of them by now. Time may tell.
On a similar not was going to start a thread last year to look at underlayment pads we have found on 67-68's Have a fair number of those documented but have not found a pattern yet.

Here are some photos of the trunk insulation. From this thread, it appears there have been very few to no examples of this found in other 65-66 cars yet. I was planning to use this on my '66 HP t-bred, but I may hold this out until further discussion or evidence surfaces. The car is so virgin original I don't see anything to suggest this car was not delivered with it. Surely not home made. Car has black standard interior. Almost exactly 32.5" long, 24.5" wide and 1/2" thick. If the trunk area became wet at all, this would have been the first thing to get tossed. Perhaps why more have not showed up.

Matt So not like other underlayment like under the carpet or over the "rear hump" on some models? Not sure why this area would get wet especially on garage kept cars or cars from the south west, but the search continues.
Called a couple of original owners of 66's and they reported that their cars never received a pad under the trunk mat - These three were all 66 San Jose fastbacks. Will maybe contact some more owners as time becomes available.
-
To me it does appear the insulation I've got is the same material in the photo SgI66 posted of the f/b sold on BAT. Perhaps in the future there will be more info that comes out about what these pads are and/or where they came from. I'm planning to reach out to the original owner I bought the car from to pick his brain about the pad.
-
Just wanted to tag on to this discussion after observing another example showing a fuel tank insulation pad. We can see this pad under the trunk mat in the photos posted in unrestored '66 section with title, "Early 66 SJ A Code GT Convertible."

I had the same underlying in my mostly unrestored 65 SJ fastback. I put it away as I was thinking it was put in later on. I am going to check if I still have it and will post some picture if I still have it

To add to this discussion. I bought my December 65 Dearborn built convertible in 1977. It had the same fuel tank top insulation as 21.4 posted, or very similar to it. In 2013 I bought my October 65 Metuchen built convertible from the second owner. It had the same or similar insulation.
Both of my convertibles have the standard interior. Neither car is equipped with anything special. They are just several of many that Ford cranked out thousands of: 289 2bbl, auto trans, radio, WSW tires, tinted windshield.

Might help if posters that have found an insulation layer below the trunk mate would include what interior (standard or deluxe) just in case we discover that is the key.
You can just go back to your post and add the info rather than adding another post :)

65 San Jos? 27Q, Deluxe 62

Ran across 30 June '66 projected built SJ Conv std interior that sold on BAT in 2020. Shows a photo of large section of brown insulation stuck on top of fuel tank. photo attached and link included to confirm plant and date from data plate. https://bringatrailer.com/listing/1966-ford-mustang-206/

Here's a 1965 convertible on BaT as of today, 2/29/2024. It has seven photos of the insulation/sound deadener on top of the fuel tank. it is pretty beat up, may not be original, but it's old. Looks like the ones in my 1966 convertibles.

It looks like fairly good shape to me because it is all in one piece.Yes it looks original to me.

+1. Very nice example.

Another example of trunk insulation seen in photo T18 of the Early 66 SJ GT A code convertible -Unrestored
Picture threads. In this example, car has deluxe interior.
