have a 1980 k-5 blazer

I am trying to put my new to me blazer together I bought it a few weeks ago. After sitting for two years this baby started right up but when I started really looking at the engine there are hoses not going anywhere and I think the blower has been removed most of the electrical was also cut apart. But the issues I am having it I have an edel carb and they had the middle hole going to the break booster and I changed it to go back to the PCV valve and now I need to find another vacuum hose for the booster but have yet to find one I still have the tower thing that is behind the carb but it is has hoses and they are all plugged up with screws and stuff but none seem to be the size I need. dose anyone have any ideas on where it all goes? Plus I have the hole on the right side I heard it should go to the auto trans but I am not seeing anything on my trans that it should go. So I am at a loss at the moment.
