After realizing that my TB adapter was not as wide as the ones used in the writeups, decided that there was sufficient room to run the brake booster line and the pcv line here. Needed the extra "meat" of the plastic in this location to drill the (2) 7/16 holes and thread with the 1/4 pipe tap. Booster line is 1/4NPT to 1/2 hose barb, pcv is the 1/4NPT to 3/8 hose barb. And yes the tap HAS TO BE a 1/4" NPT (national pipe thread) aka. 1/4-18.
