Seat back position / angle?

How do you adjust the seat back position?

I read another thread and saw I didn't have the correct HW.  So I ordered the parts and installed it, but it feels like I'm sitting in a low rider ready for a drive-by it leans back so far.

Pic shows what was originally in there and put my seat in good position.

I tried adding washers to "correct" HW but running out of threads.

What am I doing wrong?

I have  a 71 road runner with buckets and the seat back leaned so far I couldn't drive it. Turns out my very over weight son broke the seat back and didn't tell me. I was able to remove the cover brace it up and weld it and it feels like new.

You're probably on to something.

My seat has never latched.  I don't have to push the release to tilt the seat back forward. 

I was under the impression this bumper set the tilt of the seat back.

What area did you take apart / fix?

Check out this thread. I included a few pictures of my broken seat back.

yep mine cracked in the same place. I was able to weld in some flat bar across  the crack to help spread the load.
