Torsion Rod Adjuster Stuck

Here are your options. Do you have a cutting torch? If so torch the bar then or the bolt. The bar is easier on the car and you have less of a chance ruining the arm. No torch! see below

Drop the arm as stated. First you should take both the nuts off of the strut rod. Both ends doing the front first. The rear nut will hold the bar while taking the front off.

If your car has a stabilizer bar take both end links off

Remove the nut and washer off of the pin going through the K-member from the Control arm .

Remove the torsion bar clip if no done already

Drop the arm . It will drop farther once the strut rod nut is off of the front. Taking the nut off of the control arm side? The strut rod after the nut is off it could loosen up while hitting the arm back. That's a good thing

Hit back on the lower control arm pin with a soft metal drift until it is flush with the K member.

Once it is back flush against the K member. tap the control arm front at the torsion bar. This should loosen it up. If it does move back but still tight. You could then use a toothless vise grip!! after removing grease and paint off of the bar with a razor blade scraper at an area where you can clamp the bar and hit it out the rest of the way. "WARNING" Do not use a vise grip or any clamp with teeth. We use a Dodge collar with a piece of steel welded to it to hit on. You will ruin the bar if you scratch it with teath and can promote it to break at that area.

I you do not have luck cut. Get a torch and cut the bar . I have every size bar here I can help you with. I get $35 each for them or $65 a set plus ride . The bolt and swivel are $10 plus ride cleaned and ready to use. Lower arms cleaned and primed are $60 each plus ride. New rubber bushings installed add $20. I have two ready to ship if needed. These are non-stabilizer arms

I also have arms for stabilizer and the bar they are a little more money and you must buy all three pieces.

I would recommend 892 and 893 340 bars on your convertible they are sold as a pair unless there is a single that I had to cut one because of removal problems as you are having. Yeah I am getting to old to swing that hammer. If they don't come out easy they are not worth my time. I only save what removes very easy. If only these parts would fall off themselves.
