Jimmy GT, '92 GMC forever project

[SonomaZ]

So another fairly productive weekend in Iowa in the books.
Since my last visit where we got the axle tubes cut to length, the Millerbuilt ends welded on, and most of the rear floor cut out:

Cut off the tacked-on frame height setting "feet." These were just for construction purposes and kept the bottom of the frame level and 4" off the deck.
The axle is now back under the truck with tires bolted on for the first time and not just sitting in the wheel wells for pictures and measuring.
And it looks like we got the width right!! (Measure twice? I think it was more like 5 or 6 times.)
The sidewalls of the 335's should tuck right in with just a little fender lip roll.
We made some 2x4 "struts" for the front since I don't have springs for the coilovers in front yet. And with that, we at least have a roller which became very necessary later in the day.
I do have a pair of 650# Hyperco springs coming, but they didn't make it in time.



After achieving roller status we picked the engine and trans up off the temporary mounts with the frame rack hoist, cut and re-tacked the mounts back in place exactly 8" rearward, rolled the chassis forward and reset engine and trans in their new position.
For those following along, the previous decision to stick with only 4" of engine setback went straight out the window when it was realized that the true level of firewall chopping wouldn't be that much different to go the full 8, and once it was decided to just pitch the factory HVAC out that same window. I'll put a Vintage Air slimline unit in there later.
In this new position, header modifications will be reduced dramatically. The passenger side is a virtual bolt-in right now. The headers are '96-'97 LT1 F-body 1-3/4" primary longtubes.
The other victim of the engine setback besides the HVAC on the pass. side will be the factory pedal "box" firewall sheetmetal that juts out for your feet on the driver's side. It looks like this will be overcome with a relocated pedal setup from Tilton or Wilwood. Every decision always has consequences, right? Pedals, steering wheel and seat(s) will all get moved back about 4". Dash stays in stock position as there shouldn't be any required cutting up that high.

I'm sorry I didn't get pics up from the last go-round but my phone camera lens is messed up. I might put them up anyway. Thankfully my son came with this time and snapped a few with his. Will get those loaded up here shortly.
