Originally I chocked it up to the lower bushings cause yes you are correct the kit didn't come with lower bushings. And the other night I crawled under it to see and 1 of the bolts had looked like it possibly moved a slight bit. But not anywhere close to explain the excessive caving in. If baffles me nothing nowhere gave in to allow the caving and toeing in. With as much as they equally and that being something else is they equally pull down and in so I figured to achieve something like that either both upper ball joints would have to have snapped or the pitman and idler arms give somehow cause that center link I thought would have to drop quite a bit to allow both to equally drop so much. But after my buddy's suggested the torsion bars not being clocked right to keys I'm starting to think that's the only think that would make any sense of this is that the bars are not putting enough pressure on the wheels to keep the tracking correct in reverse. I'm just not familiar with torsion set ups thought they only were 4wds and I have never had a need for a 4wd so my knowledge with it is mootIf you can, get one more video of those 2 bolts to the right of the Torsion Spring, kinda close. Make sure to hit a few small bumps like you did in the video above.
Judging by the dirt/grime I am seeing on the lower control arms. I am guessing that bushings/lower arms were not part of the kit. And my eye is telling me that there is the problem..
BUT.. it should be doing the opposite of whats its doing if thats the case. Me and 2 of my mechanics agree on this.
So I am at a loss..
