Instrument panel question

[Job]

I purchased a used replacement dash panel for my A, oval speedometer. In trying to install it today the screw holes do not line up. It's like it is too small. The top screws fit, but the bottom edge will not push in tight against the dash. And the screws holes are off about 1/2" on each side. The holes on the chrome panel are too close together.
My guess is it's not model A. Suggestions? Ideas? Thanks
