Fastback fold down seat not folding down

It’s all about adjustment! You may need to loosen all four body bolts and shift it around a bit.

My car had 4 long U shims behind the body bolts and between the bracket on the driver side and only 2 on the passenger side. These cars were not so squared up when built.

I assume they were there to align the seat bottom to the rear floor area, but impact the over all alignment.
