my first thread didn't get any response so i'll try asking it another way.is there anyone who can measure the frame rail on there 67-8.I need a measurement from the ground up to the bottom of the frame rail near the rocker where the frame is level and the other measurement is from the ground up to bottom of rail where the leaf spring mounts in the back of car.this would be a huge help for me and i will try to return the favor anyway i can.thanks for any help you can give me.(the reason for question is when i got the car it had new frame rails and i don't think they are in the right place because i'm putting on new quarters and i really have to pull up on them to line up with tail light panel.not sure if thats normal but i wouldn't think that it is)

 

I don't have a first gen Camaro so I can't help you. Perhaps if you post your question in the first gen section you might be able to atract the attention of a first gen owner. Good luck

 

I'm hoping by now you have your answer. I purchased the assembly line manuals from Classic Industries before tearing into mine for the same reason. If you still need the numbers let me know and I'll get them for you! -
