It's easy as sin...you mark it while it is all on the car...yank them off...have them welded up...then...while the front header is off...ratchet the motor forward...and I had all the wiring/MAP/EGR deleted/misc engine pull brackets gone and the hood off...I turn the header sideways and seriously slide it right down...it works better if the car is jacked up a bit because especially if the car is lowered the DP will hit the ground before you can get it to clear the rear head/RVC bolted to it...maybe its just me...but do you guys that have pacesetters want more pics of it? Maybe it'll help?
