Well, I finally had the time to install the motor and tranny in the car. After my last update, I slightly ground the exhaust manifold flanges on both the driver and passenger side and this gave me just enough clearance to get the flanges past the frame rails.
I just have two pictures, as I was doing this by myself and didn't have much time to take pictures until everything was done.
Front view of the oil pan. It sits about 1/8" above the bottom of the cross member.
I was starting to re-install the front suspension, but ran into some issues. The SPL tie rod kit had the wrong size nuts to lock the tie rod together. Then one of the OEM Z32 tie rods has some damaged threads so I could not reinstall the passenger side tie rod. It uses a M16x1.0 thread, which I did not have a die to repair or find one locally. Hopefully I can find one tomorrow to buy or borrow to keep moving forward.
