Success! As of Saturday its finally back to being a roller!
Felt like it took me forever, but I got the second shock tower fab'ed and welded up, then took a deep breath and did this:
Tacked the shock towers back on and checked clearances once again. At full droop on the passenger side and full stuff on the drivers I've still got a very technical 'finger width' of clearance between the notched area and the coil, which I'm happy with. Picture makes it look like the back of the shock is closer to the shock tower than it really is, this is with the axle beyond full droop, basically hanging off the shocks.
Got some springs put on the coilovers and everything bolted up, and got to set the scout on all 4 tires for the first time in about 2 years:
In my moment of triumph I thought i'd at least roll the truck around a little, but no joy, the back tire was bound up against the back edge of the fender, so I made the cut along the lines I'd laid out to match up with the EB flares.
So that's where it sits now. Feels like its taken an awful long time to get to this point, but I am overall pretty happy with how the end product has matched up with the design I came up with in SolidWorks.
I tinkered around a bit more, got most of the TBI bits off my storage shelf and onto the motor. I was concerned the big old OEM brackets for the AC and alternator/PS pump wouldn't play nice with the inner fenders or what's left of the core support, but it looks alright. I did remove the duct that was through the hole on the passenger side to make room for the AC compressor.
I think I'll still cut out most of the existing structure and build out a new bolt on support for a radiator once I sort out which one I'm going with.
