On the question on the vacuum tubing, In the photo in post 359 it looks like the vacuum lines are both present. You can buy the short lengths of 1/4" steel tubing from Napa and cut and bend to the required shapes. I believe that would be a lot cheaper and faster than having them made by Classic.

The typical routing is using a shared fitting with the power brakes, the metal tubing leaves the manifold port below the carb and curves down and then forward to connect to about a 6-8" length of rubber hose going to the outlet of the vacuum pump. From the inlet of the vacuum pump another short hose joins another almost straight length of metal tubing visible just above and clamped to a special port plug on the longitudinal oil passage. That tubing goes to the rear of the engine where it bends upward for maybe 8 inches and then connects to another length of hose into the wiper motor.

For 54, if there was a windshield washer with the electric operation and coordinator, a tee was placed in that last section of rubber hose below the wiper motor to also supply vacuum to the washer.

The early pumps had solid metal connections at the pump for the vacuum tubing but I believe on some if not all of the later cars they had switched to a pump with ordinary hose nipples and used the short lengths of rubber vacuum hose to connect to the steel tubing.
