More work accomplished:
Finally installed my heater core shutoff (been sitting on my work bench for probably over a year now)
Final locktite and torqued in the motor/trans. Started wiring:
Got my speedway o-ring to flare power steering line adapter. Worked great.
I also managed to get the passenger side manifold off without any issues. Ordered a bunch of parts and just got them in, so now it is just waiting on me again!
