68-70 should all have the same forward tilt. I believe the only different between the 3 years is the 68/69 do not need the bent up section of the top rail where the rad shroud attaches, as they uses a metal top panel to attach the rad compared to the 70 that uses the plastic shroud to retain the rad.
I believe the difference between the 70 GTO and Lemans is only the top rail. Again, not 100% sure, but basing this on seeing them years ago.
If you are looking at a repop 68-70 support, hold the bottom rail flat on the floor as dataway suggests...if the sides/top are leaning forward, you have a good chance of an easy fix to simply graft on your top rail. If the top and bottom rails are parallel to each other, you are in for some extra work.
