Coupe/vert trunk lid fitment tricks? Anyone get rid of the torsion spring

[Bentworker]

I’m assembling my coupe before paint just to double check everything.

The trunk lid is driving me nuts, I have not yet figured out how get the thing to set flat.  Since it uses a single torsion spring the passenger side rides high.  
 

Is there some sort of trick to this?  Normally I’m pretty good at fitting things up.

I’m about ready to ditch the torsion bar and go with twin pneumatic struts or something similar to apply equal lift force to both sides.

The attached photos show how my trunk torsion bar is set up. I have not had any problems with the lid fitting correctly. Both hinges move freely.

On mine it appears that you could install a second bar for the left hand hinge if required. The hole in the left hand hinge is there and the tensioning slots on the right hand side are there.

If you are doing before paint then can move a lot more. You can put a LH spring in but you have to locate from a Cougar they had two. I sold the last one I had. Lifts the trunk with spoiler on vert or coupe. There is lots of slop in the mounting holes for the trunk and remember Ford just bent them to fit on the line. They did not just bolt on and be right. People today are crazy with gaps that nobody looked at back then.

I got ahold of West Coast Classic Cougar and buying a pair of the cougar trunk springs.

They should show up this week while i am working.  Going to try them out and fidget with the trunk fitment more next weekend.

That's how I did for my fathers vert. He complained about that his trunk lid wouldn't stay open with the dealer added spoiler and it even knocked his head several times by falling from above. So I went to WCCC and bought the cougar trunk springs from 71-73. Fitted just right and my fathers head is now safe!

You need right left torsion rods for the trunk to be flat and to work properly

Can you explain this? I didn't realize the torsion bars affected the trunk lid alignment. Thanks.

Not sure I can explain completely as I’m searching to replace mine, but what I have run into is that there are left snd right torsion rods, they have to be “wound” in place to pick up the trunk lid evenl, if only one rod, the lid is torked and will not close evenl.

My 73 Mustang convert. came with both left and right springs. I removed one as it was too much. Now 15 years later, I wish I still had it. The lid stays open if there is no wind. Needs the 2nd spring.
