we just came across what was sold to us as a '46 but we're having problems verifying that...

i have confirmed the engine to be a 216 via the casting stamp, and have managed to find a bundle of number on what was left of the "vin" plate..... they are as follows

58 - lower half center of plate
2 5727 - left hand side of plate
9BL41 - bottom center of plate
5092 - bottom right hand corner of plate

any information would be greatly appreciated!!
