i have the front of my bird off also, just as HO4SPDTOGO , i will align from my doors , to my fenders and hood. then the front nose you need. i would leave my grilles , and bumper off till last. install as a whole piece with the two bolts on each side that fit thru the frame. i have the mounting curved brackets on the front nose( that connects to the frame .) then attache the front nose to the frame. it will be no quick bolt on job. i will have to make adjustments along the way. it will take time and adjustments. and more adjustments.
