Fastback fold down seat not folding down

Just recently put some seat covers on the rear seat and when I install it, I can only get the seat to fold down to about a 45* angle before the cams hit the brackets that the bolts go through to attach the seat to the car.

I took pictures of the brackets so I could get them back on the same way and everything looks identical to me. it's almost as if the cams need to be pushed in another 1/2" or so a piece but they are in as far as they'll go. Anyone have any suggestions?
