I just joined the AACA, and will be showing my '66 Crown this Oct in Hershey. They want to know what model it is. I went on the Imperial Web Site, and it said the series number is BY1-M. Is this the model number? Also where is the engine number located? I know the vin number is on the front door jam. It's a '66 Crown 4 door hardtop. Rich W.
