The U25C, U28C and U-30C are were the same length. Were the cowling door locations and side filter locations the same for all three models?. If I were to buy a U30C model, and paint it in a U-25 era paint scheme, would I be wrong as far as the details of the engine sides and other specific appearances ?
The U25 was a very different animal than the U28/30/33/36 inside and out. The others were pretty similar with the biggest difference being the radiator cab.
