Just purchased a 74 Mav, 4 door, 250 inline 6. Already had the tranny rebuilt, starting tune up. It is missing several vacuum hoses, have not been able to find much info. I was told you have to remove and plug the vacuum line to the distributor to set the timing, but there appears to be two vacuum hoses there (??). This is a project with my daughter, having a fun time so far .
