I thought I would repost this over the weekend just in case any of my fellow 150 owners might have missed it when I first put my request for this airbox cap out on the forum.-------Wanted to buy winterization kit carburetor airbox cap.This is the cap that attaches to the bottom of the carburetor air box with four rivets. This is the only part that I need to complete my winterization kits installation. I have found the part Commercially but they are crazy expensive just thought I'd check to see if anyone might have one that they would be willing to sell. If you look at the illustrated parts catalog for the1974 Cessna 150 L figure 54A item number 22 part number 0452006 –1 this will show you what I'm looking for. I really enjoy flying in the winter here in Ohio last year I did about 20 hours from November through February and the extra heat in the cabin that the winterization kit provides would be a nice addition to my aircraft.
