Some progress.
Removed the engine/tranny. I decided to drop the tranny from the bottom, and pulled the engine from above. Normally I'd pull the engine/tranny as a whole, but with the core support in the way, I figured pulling them as separate units would be easier. Also, I couldn't get my wrench around a few header bolts (not sure how my friend installed it), but a few minutes with the sawzall solved the problem.
Pushed the car outside for a quick wash of the engine bay/underside.
A couple of hours later, the front suspension is gone.
Hopefully I'll have the shock towers cut out in a week, and have the DSE stuff mocked up.
