Torsion Tube Re-installation
Im currently in the process of deleting my torsion bar to install coilovers. Ive got racers edge delrin bushings installed but cannot seem to get the torsion tube to clear the hooks on the torque tube. It seems that the whole assembly is tilted towards the rear and cannot align itself properly when i jack up ends of the torsion tube. Ive tried with one side fully connected and now i have both ends unbolted but cannot seem to get the correct angle. Looking for tips on getting it aligned and trying not to dissemble the entire rear end to get the torsion tube installed. Please see attached pics. Any help will be greatly appreciated.

I remember having an issue similar to this. I have solid mounting points and delrin throughout as well and it made it a real challenge to get the tube back in place.
A large part of it depends where you are supporting the assembly when you are lifting it. IIRC, I had to put a jack under each rotor to be able to manipulate it the way I wanted to. I think lifted the tube itself with an ATV jack.
I also know some people have ground those tabs off...

See if you (or a helper) can pull backwards on the transmission while trying to raise the torsion assembly up.
I wouldn't be surprised if the trans/torque tube assembly were slid slightly forward due to the back of the car being jacked up...the transmission hanger mount is really flexible.

In your second picture, it shows that the torsion tube housing is too low; the dovetails need to engage between the torsion bar tube and the torque tube housing. You need to get the center of the tube up higher.
Last time I did this, I remember having a heck of a time getting the dovetails up past each other and engaged. I recall a really big pry bar seemed to make it work. As V2_Rocket mentioned, try to pull back on the tranny while raising the torsion bar tube.

Im gonna try this and see if it works. Im thinking the rotors / swing arms is keeping the assembly tilted towards the rear causing it not to line up correctly, even if theres no torsion bars installed.
Ive tried moving the tranny upward and got so play there but will try and pull trans back, both front and rear are up on jack stands
If all else fails ill just grind down the hooks, lol. Thanks for all your suggestions. Will try and post results.

In your first picture there is a bolt slid in where the torsion tube bolts to the car. When we did this a couple months ago we had no success getting the hooks to line up if we slid that bolt in first. There was one other "gotcha" but for the life of me I can't remember now. Should have taken some notes, though we all swore we wouldn't do that again so it didn't matter.

Finally got it in and i didnt have to grind off the tabs. I first loosened everything, took out the bolts in the torsion bar covers to the chassis. Placed a floor jack in the center of torsion tube carrier, then proceeded to lower a few inches. I then placed the swing arms / rotors as high up as possible on bricks, then used a scissors jack and plywood to jack up the banana arm up on each side ( scissor jacks ) to get the whole assembly level. Once it was level, I jacked up the center floor jack and everything went in smoothly. Just dont forget the have the upper torsion tube mounts installed, like I did. Thankfully I didnt have to undo the brake lines, but had SS lines and a Promotive bleeder just in case I needed to. Just want to get her back on the road to enjoy like everyone else. Thanks again for all the suggestions and help. -Wayne

Bolt the solid torsion mounts to the torsion tube assy. Not to the car. Then bring up the assy to the car. You will see it works without issues every time. Since your still using the rubber lower mounts I would recommend a lubricant to help slid it back into place without binding. And yes I see you got it.
