Jim Palmer, Jim indicated his 1967 Alon had non-sliding stock bucket seats. I just spoke with an owner of a '66 Alon with a 200+serial number, but I forgot to ask him about sliding seats. But "The Ercoupe--A Touch of Class" indicates on page 390, repeating an article from "Plane & Pilot", that the 1966 coupe A2-A, the 2+2 version (2 adult and 2 children) had bucket seats that were adjustable while in flight and had a 6 inch travel, rather than 4 inches.
But I've not seen or heard anyone with a slider frame. I don't really need a sliding seat, but it could be a usefull change for some. Ken Doyle Springfield, Mo Alon N5477E
