1946 BC-12D Drawings

Looking for a source for the cowl drawings for the BC-12D.

To my knowledge there are no published factory drawings showing cowling detail.

Scott,
Looking at your blog of your restoration, it looks like there are 4 louvers in the bottom cowl. Can you grab some dimensions? How far off center line (bottom dzus fastener as reference would be great), how long each louver is and their spacing from each other?

Previous owners replaced the bottom cowl with a flat piece of aluminum. Since, I need to patch the holes from the Champ exhaust, I figure I might as well try my hand at making a correct one. Will make a good A&P school project as well.

1" either side of center, 2" between vents, but as with all of those dimensions these were just .y best estimate.
