Okay, so a guy I know and I rebuilt my '90 GT last year (two cars into one), had it painted, going for a full restore sorta thing. We rushed the last day of work on the car, and neglected one thing: the vacuum system. THere's nothing related to vacuum in the car right now, no hoses, vacumm blocks, nada. Going on this info, what am I going to need to get humpty back together again and how much in parts am I looking at? I have driven the car, and aside from no brake booster, it seems to run pretty well. Go figure.

Just curious what the fuse box has to do with vacuum related questions, obviously I've missed something and I'm interested.
