Hey I just wanted to understand the question before I answered. I bolted up the headers and drilled a hole in the body near the center of the header flange. I used a rasp bit in a drill and enlarged it till I could bolt up the side pipe. Took back off and enlarged it till I had enough clearance around the pipes. Did this a couple times. First side took my about an hour. Second side took alot less. Good luck
