I have a model A frame. Based on research of the various brackets and crossmember cutouts etc., I put it at a late '29 or maybe an early '30. No serial number stamping is readable on the left frame rail under the cowl area. This is what has me puzzled: all of the frame demention charts I've seen call out the distance between the frame hole for the front cowl mounting bolt and the first hole on the rear cowl mounting bracket to be 8 1/2". On this frame it's 11". If I set a cowl lower wood block on the frame with the front bolt in the feame hole, the first rear bracket bolt is in front of the bracket, and the rear hole in the wood block bolt aligns up with the front bolt hole on the rear mounting bracket. The frame hole for the front cowl bolt is located per the frame diagrams at 18 3/4" from the front face of the middle X-member. It's the rear cowl mounting bracket that is located closer to the X-member. The bracket is still riveted in place and no extra holes showing it to be moved. What body style may have used such a mounting arrangement?
