Fastback fold down seat not folding down

Are the cams adjusted all the way inboard on the cross shaft? You can see the set screw in your pic.

if so you may need to space the mount brackets outward with washers and or shims between the seat frame. Particularly on the forward bolt in your pic. Has this been mini tubbed?

Yeah I pushed on them as hard as I could. One of them is flush with the shaft and the other is sticking out just an rch but it wouldn't make a difference if that one was flush as well since I need even more room than that.

I was thinking about shimming as well but I don't remember the seat not folding down when I got the car but I basically tore it apart as soon as I got it so there's a chance that I didn't even test it. I'll give that a shot this weekend and see if it works out.

No mini tub. It's all stock.
