[Spridgets] Question on seat frames

[Billy Zoom]

The 70’s seats have the chrome side lever to lock the seat back, and the back is about 3 times thicker than the MGB style seats in the 65 - 68 Spridgets, which are about 4 times thicker than the early AH style seats. 1969 seems to be an orphan. I don’t know how thick the back is on a ’69.  If it’s a lot thicker than the ’68 and has the spring loaded back, then the 70’s upholstery should fit. ’68 & 70 are different seats, and the mounting rails & holes are also different. You’ll have to figure out which style a ’69 was more like.
