Anybody have a homebrew way to check frame straightness?

As the title implies, I'd like to check at least the front section of my frame. I havent touched my bronco in a month after snapping the front axle housing in half after a small, unforseen jump... When I open the drivers door it rubs the door frame at the top where the roof and window meet. It landed hard, hard enough to bottom out the trac-bar mount to the frame, trac-bar to oil pan (slightly) and completely compress the 4" rubber bump stops... so until I get the axle fixed, I might as well see what else I can or already did break

you could hang "plumb bobs" from the body mounts, and then take measurements between them all. measure down the sides, as well as Xs between them.
similar measurements between left front/ right rear, right front/ left rear etc, will indicate a square frame. if you have numbers that are way off, you can at least calculate which way what is bent where

that pretty much describes what i did to figure out what was tweaked on mine. i would be curious how close your numbers are to mine. my frame appears pretty straight, but the center pins/bolts on both leafs were demolished, allowing my rear end to not be parallel to anything.
this is the final diagram from all of my measuring, hope it helps. i have it in a PDF, but it is too large to post.
