I mounted the rear cab lights, because the time I was following it back to Missouri to turn in the rig for a company I drove for, my brother was driving it, he'd get far enough out in front of me and the taillights just didn't do much for illumination, I also have some under the light bar and two little side fender lights similar to what I believe Saab does.
The flex, I dunno, just 4" Rough Country springs, lower first leaf removed, sway bar disconnects, the rear are stock, 4" blocks, I did add a couple of leaves from another pack to gain some height from the old saggy squat it had, in doing this, I cut the little wrap around tab that keeps them from fanning out.
That sway bar removal alone gives a TON of extra movement though.
it's been stuck in Indiana, for the past 2 and a half years because of a random fuel injector signal pulse failure. I haven't pinpointed the exact problem just yet, not living there any longer so I have limited time on working on it when I do, I tried to drive it home a couple of years back now when I thought I had fixed it, but it quit working in St. Louis, MO. So it's been sitting there ever since. One other time we drove back there last year, I bought a complete new (not reman'd) distributor, but that still didn't even cure the problem. So I have pretty well determined it has to be a wiring harness issue. Trying to work out details on either getting it hauled back here to Washington now, where I live, or getting back there myself to attempt to fix it again.
The tow truck one was when the alternator decided to have it's rear bearing fail and pretty much catch fire, leaving me sitting on the side of the free.
