I just got an edelbrock 3706 manifold and it dosnt seem to be a place on the manifold where the break booster vacuum hose would go. on the stock manifold it screwed right on the front. has anyone else had this issue with this manifold?

 

The hole is at the rear of the carb mount. It not gonna be just like your tbi intake, so expect some modding w/ the throttle bracket too.
