Finally got my springplate dilemma fingered out, all I had to do is switch them back around one more time. The drivers side goes in no problem and I get it bolted up to the T-arm. I start the passenger torsion bar in and it stops an inch out like it hit a cement wall. I take it out several times and retry all to no avail. I unbolt the drivers side and try that bar and it stops in the same exact spot. I can't see any obvious problems with the splines anywhere. I run some towels and grease through trying to maybe clean out some unseen grit buildup. I assume there's a burr stopping the bar. I get an idea to knock a bar all the way through from the driver's side to try to remove the burr. I should have stopped short of 'all the way''. The springplate end has a larger spline and won't fit through the spline in the torsion tube. So I reverse the bar back through hitting it through the passenger side with a piece of solid SS round bar. It's engaged in the splines but it won't move. In a matter of a full hour of smacking it(and myself) with a 12lb sledge and heating up the tubing with a rosebud I get about 1/2" of movement back. I could spend an 8 hour day smacking this thing and it might still not be close to making it out.
Now my options are:
Cut torsion bar where it's sticking out and knock it out towards the passenger side hopefully saving the splines in the housing and hopefully being able to knock it to the passenger side easier than the drivers side. Downside have to replace bar and it might still be stuck in the end.
Or I could do surgery and cut out the splined section of the torsion tube with the bar inside and then split that splined section so I may remove the bar intact. Then hopefully the weld a new splined section back most likely in the form of a torsion adjuster which is an upgrade but nothing I was planning on doing. Downside, the torsion tube could move when I cut out the middle since it's been welded and heated up so many times making welding in a new splined section a PITA.
If anyone has any suggestions I'm all ears. Last night I was about to haul the whole thing down to the curb and set it on fire.
And from what I've seen just on this website alone, you do some phenomenal fabricating! My hats off to ya!! 
Back to the subject of stuck torsion bar... I had somewhat similar problem with mine last year. Broke torsion bar on a ride and it broke just shy of the inner splines. Tried and tried and even tried some more to get it out and never succeeded... Ended up airbagging mine, WELLLLLLl worth the investment to say the least. But not sure if I'd go thru the trouble airbagging a swingaxle. But sometimes you gotta do what you can with what you've got!
