sparkles

Thank you thank you thank you!! The last piece of the puzzle is the bcdd and I'm set, I believe the 73 is electrical, but this one is vacuum! Thanks a million!

I have a 73' 620 with a 74' carb, I got the carb back from the shop ready to go, but I am having a heck of a time figuring out where the vacuum lines go. Any help would be hugely appreciated!!! There are three hook up spots, two on the side near the engine and one on the BCDD. And one line coming off the distributor. (I have pictures, but not sure how to post them. First post woohoo!)
