Call a classic car junkyard or check Hollanders for interchange of the tank with other models and years. A Cutlass/442 has lower capacity and is not a direct, correct fit.
I just went through this with my ‘66 98. Turns out the tanks for that car are 65-66 98’s only. All others are different.
Thanks for the advice. I just found out about a rust remover “Evapo Rust”, I think I might try cleaning the rust out of my old tank myself with this product. It has excellent reviews, and find someone to rebuild my sending unit.
I had a '67 Delta 88 that needed a new sending unit, and I found that this one, Spectra Premium FG-106A, available at Rockauto for about $50, is a drop-in replacement. It's designed for a baffled fuel tank, and the tank on your car is not baffled because the baffling is supposed to occur in the sending unit itself, which is a hockey puck sliding up and down inside a tin car. So the gauge will wave around more than normal, but it still works, and at least you know how much fuel is in the tank.
Have you actually removed the sending unit on your car? As I said, it's an unusual float-in-a-tin can arrangement. Here's a photo of the unit that was in my car.
I tried to clean and re-use mine, but I could never get the float to not get stuck inside the can, so I replaced the whole thing.
You can see the little holes in the tin can in the second photo below. The fuel enters and exits the can slowly because of the small holes, and that's what acts as the baffling and prevents the float from moving rapidly up and down when the car over bumps or around corners and the fuel sloshes around.
