Hi Jim......just in case you get to the C-Beam Plates.......
I always have on hand SS bolts to replace the Stock Exhaust bolts to the Exhaust Manifold rather than install the rusted old Bolts (6 bolts of two different lengths).
Have some HEAT handy just in case the Exhaust Manifold bolts are rusted beyond letting go with reasonable torque (you do not want to break them off....yes I have done it all).
Some other items just in case......And make sure you remove the washers on TOP of the C-Frame (did that also)

5. Why Take Measurements?
It is kind of a corny measurement since you are measuring between the C-Frame and the side wall/Underbody which is heavily coated and made of light steel and the accuracy of the measurement needs only to be within 1/4 inch + or -. I think you are just making sure you did not put an angle in that front driveline U-joint by moving the transmission appreciably during the installation of the new C4 Beam Plates.
A Quick Measurement in regard to Transmission Yoke height can be checked from inside the car by measuring the height of the Shifter.
A height of 6.25 inches from the counsel to the top of the shifter (at the center of the shifter in neutral) will be very close to the correct transmission height.
a. The 1.77 in spacer should fit between the top of the driveline support to the underbody. The 1.1 in spacer should fit between the right side (passenger side) of the driveline support to the side wall.
b. You might check that alignment spacing before you start the project to see where your alignment is now. Then just keep that alignment with the installation of the new C4 Beam Plates.
Secondary to Transmission/Driveline Alignment is ground clearance of Transmission Drain Plug. The Transmission Drain Plug clearance to ground is approximately 4 to 4.5 inches on my ZR-1s which is NOT the lowest point on the ZR-1 Drive Train/Chassis. The Ground Clearance depends on many things including Tire Pressure, Tires, Wheels, and Suspension.
6. Re-Installing the Exhaust.
The Exhaust System can be re-installed after the C-Beam Plates are torqued and the front Exhaust Hanger is re-installed in the location of the Front C-Beam Plates.
The Entire Exhaust System can be reinstalled by sliding the Exhaust System under the ZR-1 and setting a rolling hydraulic jack under the rear of the center Exhaust and lifting up to within about 8 inches of the final position.
A. Lift the two rear Tail Pipes and slip the slider into position on the slip joints. Slide the Entire Exhaust System to the rear of the ZR-1 about 1 inch completely engaging the slip joints holding the Tail Pipes.
B. Raise the front of the Exhaust System with the rolling Hydraulic Jack to the final height aligning with the Catalytic Converter Connections.
Slide the Entire Exhaust System Forward and install 6 NEW SS 10mm x 1.5 bolts. (10mm x 1.5 x 30mm on Passenger Side and 10mm x 1.5 x 50mm on Drivers Side). The SS Bolts shown have 17mm Hex Heads and Washers are NOT required.
SS 10mm x 1.5 x 30mm and SS 10mm x 1.5 x 50mm Bolts
C. Reinstall the two Front 13mm Head Hanger Bolts and the two Rear 13mm Head Hanger Bolts.
