It was this one, so it looks like it's 59" wide. It actually went from one corner of the bay to the other corner, so no problems there. I'm willing to be the engine bay dimensions of that wagon aren't different than the 90 in that respect.
If you end up getting the support bar from HF, don't forget to bring one of those "20% off any one item" coupons with you.
The tension on the control arms is because their bushings are solid and don't swivel. So, unburdened, the control arms will want to stick straight out from the subframe. You can manipulate them up and down but it requires a fair amount of leverage. When you lift the car, the struts extend to full length, pushing the control arms down quite a bit. You want to disconnect them from the struts so as to relieve that tension and leave them unburdened. The straps OP used in the other thread were simply to keep the steering rack properly supported.
