1968 camaro frame rails
 

Hey everyone, I just signed up to the site. I have a 1968 camaro with a 327, I'm currently replacing the frame rails. I measured them before I removed the right one but can't seem to find the paper. I looked online for more info and the pictures provided are not very good. I know the rear distance from left frame rail is 42 7/8ths at the rear and 33 1/2 toward the front but don't know where to measure from in the front. Center to center? Whole to whole? Can someone please help. Pictures of possible.
Thank you and I hope this isn't confusing.
