Procedure to adjust trunk torsion bars?

Ok, I put a spoiler on the trunk of my 94 cougar, and now the trunk doesn't pop up and doesn't want to stay up once raised. Does anyone know the procedure to adjust the torsion bars so that the trunk rises up again? I searched but couldn't find the exact procedure, just a bunch of people saying that they knew it could be done. Thanks.

I know about the hydraulic strut mod, but I would prefer to do it by adjusting the torsion bars since it would A)Be a factory type of adjustment, B)Not cost anything, and C)Be more reliable than a hydraulic strut.

IIRC, they are not adjustable. That is the reason for the hydraulic strut mod.

They are adjustable, but it is a PIA to do it, and can be harmful to your health.............

The torsion bars in the trunk ARE adjustable - they need to be moved to a stiffer slot. Here's a pic - see the slots labeled "5":



Here's a link to a PDF file of the instructions from the service manual - do NOT try adjusting them without reading the instructions:

Cool. I never knew that.
Here's a post showing in great detail what you need to do the mod. I think it's even better than the tech article.

Update! I've wanted to do this for a while. (The mod, not the tightening thing.) After trying several different struts from AutoZone unsuccessfully, I pulled the hood struts out of my '93 parts car. I just popped one end on the stud sticking under the rear deck and the other on the spring sticking out of the hinge. They are actually on there tight. So I just did the mod for free. Think about going to the junkyard for the hood struts. Probaby $10 or $15 bucks and that's it.
