At work we are currently working on a 54 Belair convertible that has been scabbed by another shop that closed down.
The main thing is the frame dips down and touches the driver's window.
Looking at it,  there's a connecting long arm that bolts down towards the rear seat, looks adjustable.  We thought the brackets had been flipped upside down not letting the arm to pull down.
Boss flipped em but still not enough pull to bring the center up .
Can't seem to find much info on this particular year. Any info out there.  Maybe Sammons knows something.
Usually we don't have to touch anything with the frame like this.
Car has been taken apart and poorly put back together.

I told my boss maybe to loosen the bracket and we'll prop up the center and tighten it back up.

Rattiac, dad had a 54 belair conv but all we did was put on a new top. Frame was lined up.

My brothers 67 Camaro had that problem. I loosened up all the bolts and did as you described. I jacked up, (with a 2x4 chunk) at the fold point and hyper extended it, tightened everything back up. When i released the porta power jack off it settled out right.
Thats all i got for ideas.

We were adjusting the right plates just not properly,  found info on chevytalk.com

Having the wife print em off.
Can't wait to try this out tomorrow.  Learned something new. 

Ha,ha. Me showing the old guy something is a change . He always says "if ya wanna learn something,  hang around the old guy's" 😊

Now I see why the other guy put it on so loosely.
After adjusting things,  there is so much play in the frame it hardly made a dent.  Front header won't lock down. Bent internals.
Can't seem to find parts.
