G4M1 Betty Scale Drawings Question

Just looking to see if anyone could tell me where I might find or look for a set of scale drawings for the G4M1 Betty bomber. 1/48 preferably but 1/72 will also work. Specifically I’m trying to find an accurate drawing showing the rivet patterns. Wanting to try my have at riveting an aircraft model and this seems like a good canvas. Thanks in advance for any suggestions.
