Rick, the seat components are the same with the exception of the rails on the passenger side of some. Midgets had adjustment and sliders on the passenger seat, not all of the Sprites did. The upholstery design and piping color changed a few times. Yours should look similar to a GAN2 Midget.
A small picture of a sprite wheel is posted. Sorry it is so small. It looks a lot like a Midget MK1 wheel, but has the "AH" wings moulded into the spokes.
