Take your time
Let me weigh in here since nobody else has so far, Aligning the stripes took my wife and I over 6 hours. (eternally thankful), so plan on this activity taking some time to accomplish.
My car was on the paint buck and I installed the hood and trunk using spacer blocks around the edges of the hood and trunk and temporary washers to lift the hood and trunk to the "level" position. Once I got it to the correct position, I used wide blue painters tape to hold the hood and trunk in position while I was installing the stripe tape.
Before painting I found the center of the car, and drilled several holes on the center line using a #50 dill bit in several inconspicuous locations.(underside of the radiator open, under rolled edge in cockpit, etc) When I needed the center line to set up the stripes I used #50 drillbits as anchor points. Carefully measuring off the center line for the for the stripe edges. Once the correct starting point was located, I pulled blue striping tape the full length. You need gentle pressure and patience for placing the stripe tape. If it doesn't go down the first time, try again. You get about three tries before you need to throw that piece out and try again. Pulling the full length will assure that the stripes will line up across the cowl , the hood and the snout.
When all the stripes are in place, the tape crossing the gaps can be cut with a razor blade and rolled over the edge.
Couple of additional hints: 1) Wear some type of a glove, latex or cotton to keep your hand grease off the stripe paint. 2) Nothing on these cars in straight or completely on center. The final decision on placing the stripes is using you eye, if it doesn't look right to your eye then don't be afraid to move the stripe tape until it looks good to your eye. 3) You'll be looking at the stripe tape from 2 or 3 feet away and will see a bunch of nits, most people looking at your car will be looking from 6 to 8 feet away and a lot of those nits will disappear.
Good luck and HTH
