Here is how I tied my A pillar into the cowl. I just ran some angle iron onto or as close as possible to the door hinges and around all the other spot welds.
Its the jeep lean. All the cool jeeps are doing it.......
From what I have seen they all lean a little after a few years. I think the suspension is sagged a bit on the passenger side because of the engine torque. I measured the lean last year and it was about 1.5 inches. I suppose I could swap the springs side to side to level it out, but I'm not really concerned.
The springs are not stock, they are used and abused 3.5" rubicon express with a small coil spacer and stock isolators the back is RE 3.5 with a small shackle.
