Hi so with the advice of "Father" John Tannehill and my 14 year old son we were able to straighten Shirley's frame using 4 x 4 timbers, chains and a bottle jack. We did not take the body off. See the planning discussion thread here: http://www.mtfca.com/discus/messages/708324/753776.html?1495333835 The key is that you can sight down the beams from the front of the car or the back and fairly clearly see the deflection without having to use a string or take the body off. Shirley's frame was bent at the hogshead ears which is where the weight is. So we took the body bolt nuts off, took off the radiator support rod to let it flex upward. The first try in the picture did not work because there was not enough leverage. Also don't use a block of wood 4 inch side on the ram like that in the picture because it will roll with the force. The 2 inch side of the wood block will keep the ram from denting the frame and won't roll so much. So we took the front fenders and radiator off put the chain around the beam at the front, then put the other chain equidistant from the hogshead ears and jacked it up with the bottle jack. The second time worked. The frame straightened enough. The hood and the doors fit now.

Bottle jack frame straightening.

Great that it worked :-)

Did you loosen up some bolts to make it easier to overbend the frame to make it stay in the right place? (I would have disconnected at least the front body to frame joints and the radiator to firewall rod.)

Roger, Um, if you read the text above he states that they took loose the body bolts, and pulled the radiator.

Sorry, got to have rushed too fast through that, still great to see that the method worked :-)

Yes, removed the nuts on the body bolts I also unbolted the firewall mount brackets so it could flex upward freely.

Yse, good to see it worked.I would have also put a hardwood block inside the frame rails to keep them from closing in any.
I once had to squeeze a front crossmember after the frame was done because the radiator mounting studs were too far apart. used a chain and a come-a-long and afterwards the front fenders were level with each other!! Got two birds with one pull!
(skeet joke, "PULL!!" BAM!)

When I built my shop, imbedded steel eyes in the floor to secure a frame during the straightening process. I put enough eyes in the floor so I can also pull forward and side ways to square up a frame. They have proven to be very handy when straightening frames

That's just cool.
Like Dave Gingery said to Keith K. and I many years ago. "If it works, that's the right way to do it."

"The hood and the doors fit now."
This. This.

Surely, she appreciates this and don't call me Shirley... :-) You'd be one of the few that would get this I think.
You rock Mr Valdes!
Plus hints of speedometers...

Duane, and in the background we hear the sound of props but it's a Jet. . . .
:-)
Good ol' Yankee ingenuity.
