30/31 Coupe Subrail Set-Up Measurements

[Brent]

Hey everyone,

I've been having a heck of a time finding mesurements/dimensions to get my subrails into my coupe.

Can someone pull some measurements off their car? Some info I have found online is vague or plain ol' wrong.

I'm looking for the measurement of the cross channels. I feel like I could get it figured if I had those measurements.

Thanks you all for your time,

Brent
