front frame

I realize this thread is over 2 years old but it is the only one that partially address a question I have: Fig 4.6 (p36) and the Appendix (p162) show FF4 as 630, but Fig 4.8 (p38) show that same area being 627. Talonmotorsports asked the question on page 1 and as far as I can tell it hasn't been answered anywhere.

Are TR1 and TR2 supposed to be spaced out so that the ends are 627 apart from each other, and 1.5mm inward from the each end of FF4 like Fig 4.8? Or are they supposed to be lined up with the outer edges of FF4?

I'm finding that if TR1 and TR2 are lined up with the outer edges of FF4 at 630 then TR8 and TR9 are slightly larger than they should be according to the Appendix. I think TR8 should be even with BR10, but they're not with this layout.

One other random question: some measurement on the figures have '=' on both sides. Why? Im located in the US so this could just be uncommon to me. Thank you for any help.
