Frame Staightening '67 2wd
I have my 2wd 1967 truck stripped to the bare frame and want to know from you frame specialists some simple checks for straightness. Also the rear end of the frame rails are not square and look like the factory assembled the rear crossmember in it with the outsides like this /-\ this is not a good description but the symbols represent outside to outside of the rearend of the frame which tapers out at the bottom and causes the rear spring perches to be a little crooked.

Wouldn't one use a *String, pulled Taunt* to check for straightness?

Good Job on the drawing. The method described will check for "squareness" to make sure one rail is not way out of line with the other, but it will not check for twist or bends. The collision shops actually have a frame rack they put these on. I wonder if there is something other than what you described which makes you question the frame's "straightness"?

Short of taking them to a frame shop, I would use a plumb bob on a line to mark hung off identical points on each side of the frame on the ground. Just pick a hole on the frame, hang the plumb bob from the center and mark it on the ground. Then go across and mark the corresponding hole on the other side. Make sure you are parked on level ground. After you have transfered all those points to the ground, pull the truck away and do measurements. If you have picked holes in the center of the frame, you should find them lining up fairly closely on a line pulled taught from front to back. Then do the measurement described above in the drawing, measuring diagonally across points they should all be identical, +- 1/2". I figure 1/2" is good enough, because there will be slight inaccuracy built in for marking error.
If you find any large differences, hit a frame shop and they can jig it up and check it with a lazer....

THis is definatly dangerous. I straightend my 66 F-250 frame using the Drawing I got from a Body shop, similar to the one in this topic.
This truck had been in a Fatality accident, left front to left front, and the unscrupulous gold diggers that rebuilt it just put some Wrecking yard body parts on it and painted it.
I used two hydrolic Jacks, two chains, some 1/2" Bolts, several two-by and four-by blocks of wood, and part of an old Power Pole. And I had two guys helping me as well.
You have to jack it up and rest the frame on blocks. Otherwise it wont move very easy.
With all that stuff I pulled the drivers side of my frame forward almost three inches. The Rivets didn't loosen either.
It's a creative art, and you gotta be safety concious at all times.
