First drive after brake upgrade, then - BANG!

Feel your pain brother. Stay at it.... Tech Service Manual is your friend.
Best thing I've read today. Thank you.

By the way... The torsion bar is fine, boxes are fine. Nothing is broken (like I mentioned in the original post (also why I didn't post any photos)). I assume the motor jumped out of the motor mount, then slammed back in - BANG.

Checked the height on the LCA-s they were off - car was leaning but, not now. Runs a LOT better now that the engine is bolted down properly - as is, I hope - everything else.

I had read in here that it's possible that a torsion bar can "turn" inside the box if it's rusty - that's why I had asked if I had to remove the torsion bar to put it back in place.

I've been turning wrenches since I was 15 y/o but as I also stated - I'm new to torsion bars.

Thanks to all who offered reasonable advice.
