Default Vacuum Line

I have a 69 with a 350 and I put a rebuilt quadrajet on it yeserday (along with an engine dress up kit) the problem is mot of my vacuum hose were so old they cracked off while I was removing parts and now I have no idea where the lines from the carb plugged into.... The one on the front of the carb on the drivers side as well as the one on the passenger side of the carb???

There is also the round looking silver deal that is next to the coil that had a line to it also and I do not know where that connects to???

I was excited to get my Vette back on the road and now this

Any help would be great pictures would be even better!
Thanks in advance

Most every shop manual will have a vacuum hose diagram in it,if you don't already have one,you should seriously consider obtaining one.
The line on the passenger side probably goes to the silver thing on the distributor. I'm not sure about the one on the driver's side,maybe the headlights or brake booster?

I will give that a shot tonight and play with the other ones and see how far I can get! I needed to step away from it for a while! I am looking at getting a shop manual as we speak! I can not find one at any of the stores in my area of course!
