I could use some measurements

I got the cart ahead of the horse, if you will. I noticed when I primed the inside roof of the car this weekend that when I welded my plates in the roof for the 3pt seat belts, I think I covered the 3rd set of holes for the roof bows....
Can anybody produce any measurements for these holes so I can drill them before the car goes out for paint?

While I'm begging for measurements, I ordered the dual exhaust hanger kit, can I get a dimension off the rear frame rails to the center of the muffler hanger so I can get these in too. Thanks...

So we're on the same track, there's the A pillar, 1st set of holes, second set, third set, then 4th set a bit lower on the C pillar.

Ignoring the rear hole in each set my 66 is 10.5" from 1 to 2, 12" from 2 to 3, 10.25" from 3 to 4. That work? There's not enough car left for the other measurement you needed. If you have a spare shoe box I can mail you what's left of this one!

Thanks man, you're awesome! That is exactly what I was hoping for. How about 1 more, what is the distance down from the top of the inner structure to the front hole? I can handle laying out the second hole based off measurements from the other 3 sets of holes I can see.

BTW, I don't have a spare shoe box, lol...
