Yes, but the offsets are different. The Manta offset is approx. 37 mm. The GT wheel is marked GT and is quite a bit less something like 25 mm IIRC.

Check out OGTS website, to compare the different stock style wheels:

Funny

I also have a 73. I also have just one 73 wheel. It's my spare that came with it when I bought it. I have the 72 wheels on mine. I like the look. It's unique.

If you look in my "Photos", I took pictures as I went thru the steps to sandblast and repaint the rims for my 1975 Manta. It's a time consuming effort to get the black and silver sprayed on and looking decent. You can easily find some rusty rims around and start with a good sandblasting. After that it's just time and detail.

Have a question. You say these are interchangeable but the offsets are different. What exactly will this do? I just purchased a set of 71 Manta wheels, but they are to go on a GT. What's going to happen here?

You will make the track width narrower. Not desireable for handling...

By roughly 1/2" each side. They should clear but as Rally Bob said, "Not desirable for handling...".

Check with GreenOpelGT since you're in Ohio, maybe you can work a deal with Tom for the correct wheels.

What I have now are 206 60 13 I think, with slotted mags. PO had these on. I prefer stock. Just figured they would be the same and would fit the GT.

My GT had '75 wheels on it when I bought it. I didn't know any better for a long time either.

On some wheels, the "GT" is stampd on the back, so some cleaning may be in order. I have some GT wheels stamped this way, I also have some that are stamped on the front.

I agree with BQS4. I have seen markings on either the front or back for GT wheels.

When BQS4 was sourcing some wheels for a friend we discovered this, or at least I did, Gene may have already known.

I noticed the markings on the front of the wheels on Ricks original GT and when I picked up the "Stinger", they had markings on the back of the wheels. That is how I discovered the difference.

These wheels are the 71-72 stock wheels with all the holes around them. Dennis at OGTS tells me they are the same as the GT, although they did come from a Manta. They measure 13" x 5", if you measure at the lip of the wheel. Are these actually different than the GT wheels of those years?
