And to elaborate a little, it's a good practice to use a little silicone grease on the rubber fittings. It makes tubing easier to install and contributes to an even better seal IMO. The check valves are cheap and readily available. And pay special attention to the master lock valve. Mine failed and the brand new replacement turned out to be not good. !!!??? The supplier sent a replacement and all was fine. However, the positioning/alignment with the locking lever is critical. Even a tiny bit off and it will appear to leak even if valve is good. A secondary benefit is that you can clean and lube window mechanism while door is open, though you probably did that during your frame-off.
Replace all lock actuator diaphragms on principle. Same with rubber tubing connectors. Make sure all check valves are in working order. Replace rear and front vacuum reservoir grommets where the hard line enters the reservoir. Replace vacuum valves in heating system, or at least check for leaks. Check the master lock valve, it's a common source of leaks.
Do one thing at a time, then vacuum test the whole system. If it still leaks, move to the next item on the list. Once leak free, the system works perfectly fine.
