I need pics of early ( 66 , 67 ) wagen rear seat and fittings under seat area . Please
I have a seat but not sure if its early or later ( it's black ) , will post pic soon .

Post a pic of your seat, what pattern is the seat cover?

Squarebacks have a hinge and a boxed section under the rear seat to allow the base to flip forward. (Fasty's and notch's don't have this)

Pretty sure I fit a 74 (squareback) rear seat in my 68. It went straight in.
