PDK9

okay guys, its been a while but ive picked up a new truck. 1988 toyota 22re x cab 4x4. now, i was a decent ride, some proper bed rust. guy that owned it is a friend, he had the motor rebuild then while using it to back a boat up in his personal boat launch it overheated and being it was a fresh rebuild he kicked in the drivers 1/4 and the drivers door. It will need both. Im gonna go through the motor, is there a way to simplify the vacuum lines, or are they all needed, as in could i delete some. goals will be sas, engine rebuild, flat bed, paint job,
