I have 2 vintage Tri-Power air cleaners. They are new and still in the original box but not in perfect condition. On the box it shows fits 55 to 62 Chevy V-8, Oldsmobile 57 to 58, and Pontiac 57 to 62. The paper in the box is dated 1962 so I feel they will fit many cars and trucks much newer with a Tri- Power set up. They were made by California Customs and even the boxes are very collectible. I will meet you at a public location or I can mail them to you.
