I am putting a 1967 Barracuda fastback back together. I put in a new trunk floor from AMD and take note of the hole for the fuel neck, some sort of polygon.

I bought a fill filler neck gasket to seal around the hole, and it is no where close to fitting. Maybe it is for a rear filler neck on a valiant, but it does not fit a fastback 67 Barracuda.

Does anyone know of a supplier for a gasket that will fit the hole I have?

My understanding is the AMD floor is actually a 68-69, which uses 2 gas tank straps, not the 1 that the 67 uses.
 
Thanks for the heads up on the AMD part. I installed the AMD floor, and used the existing one strap with a new gas tank and it worked/fit fine. Have not tried to fit the filler neck in yet, but need the gasket before fitting that in.
 
Thanks for the kudos Steve.
Look into my build thread

67,68,69 cuda dilemma

It's at top of page 23 in the thread with the trunk floor install. I did not want to use the 1970 up filler neck gasket. It's a minor modification the the new pan. Plus filling and redrilling a few holes. You will need the old section of floor in that area as a template. Lots of good information in this build you can use.

Hope this helps

I'm pretty sure you will need make the hole match the 67 and not use the later gasket.
On the fastback there is a wall that the load area floor attaches to and the later gasket would interfere.

Thanks for the info. I have the new gasket on the way. The trunk is all welded in, actually the car is near ready to paint, so I will be doing tactical adjustment to make it work. It seems all the first year series Barracudas have some interesting issues, 64 1/2, 67, and 70. I have very early production number cars on gen 1 and gen 3, the gen 3 being an early production convertable.

Now is the time to fix it, you really do not have a choice.

Has the floor support been put in yet?

The metal work on the entire car is done, this was discovered when I tried to put in a gas tank. I guess I will have to cut what I have to cut, and then add support where needed. I added torque boxes and put agitational metal in front of the valence that connects the 2 frame rails together. I will take some pictures when I get into it. The picture in the top of the post is what the floor looks like.
 
The hole in the fastback floor is exactly the same as the coupe filler hole I modified. The only difference is the bend in the filler neck tube for it to tuck under the metal sub floor deck.
