Eric. I own and maintain a 1965 C337. Yes the P337 will fit your hangar size. Mine sits about 2 feet from the trailing edge of the wings. and the wing tips are about a foot from walls. About 1-1 1/2 feet from the rudders trailing edge. I received my flight training here in Western Pennsylvania and basically stumbled across my CFI/MEI here at my home airport! Finding a DPE was more trouble, but found two, one in SW New York and another in central W. Virginia. I had about 900 hours as a Pvt single engine/100 Series Cessnas. When I started training in my Skymaster. Had about 50 hours when I was signed off to take my check ride. I did find another CFI/MEI in Nashville Tn. I needed a second MEI sign off, he was a good and understanding instructor. As for where to find a Skymaster, two web sites come to mind. First-BARNSTORMERS.COM, the other is SKYMASTER CENTER, the company is in South Carolina. Prices for a good P337 start around $100,000 with mid-time engines. Skymaster Center offers a Re-manufactured P337with new engines, special additions like winglets and new instrument panels, etc is about $425,000. If you have further questions please feel free to contact me directly at

Good hunting.
