Good morning Torbjorn and to all,
This can get to be a lengthy answer, but the short answer is locate someone in your area that has a frame puller at a body shop and see if they have reference points to measure from to guide you. In todays world with "throw away cars" that's becoming a lost art.
Now if the car is stripped to the shell, I would try to locate a relatively level area on the shop floor and with jack stands support the body squarely.
Use a plumb line from the H frame attachment points and make "X" marks on the ground in those spots. Then measure straight down. Note your measurements, remember these cars were all built on an assembly line and there is a reasonable amount of error. I wouldn't be surprised to see at least an 1/8" or .125 or about 3mm difference in any spot.
If you find a level spot and support the shell and it doesn't rest on one jack stand - measure that distance. You might have to shim up that spot.
Don't worry about the radiator support chassis mounts you can shim them
for what ever amount distance you might need. If you find a distance like I'm describing then I would suspect the H frame will be bent in that location roughly the same amount.
Chances are good the car can be "twisted" some and still be usable, but the straighter the better. This where a good body man and/or frame puller will get you in the ball park. Just remember a ruler, bubble level and a framing square will never lie to you .If its bent or crooked you'll know.
Mr. Southerland reminded me of the frame holes that were missing in the 1967 frame I installed At the time I tired to replicate the holes and locations so it all looked correct. When you're young and have lots of spare time you can accomplish quite a lot. Thank you Dwight for reminding me of those details
So get out into the shop and roll up your sleeves and get to work!
have a good holiday season and have fun.

Respectfully,

Unfortunately, some of these old race cars have been built using salvage yard donors. And they were in the yard for a reason.

I've seen a few, not necessarily S/SS cars, that were twisted bad, and not really redeemable.
