68 barracuda lower side stripe

hi guys this is my first post and need help i have a 68 barracuda in my shop and i am going to paint the lower stripes on and need the dimentions also i need to modify the rear valance panel for dual cutouts and need the dimentions for that also any help would be awsome

Hope this helps. My camera won't zoom in very well!
These are of the door stripe and the front fender. I have already stripped the body to bare metal so the 1/4 no longer is there. This is probably the worst tape measure I could find Lol!
