34 frame bent

I have a couple questions about straightening my frame. first off I was thinking about putting some anchors in my garage floor . How many should I put and how far apart do they need to be ? The frame is bent in slightly at about the firewall and down a little in the same spot. I measured and its out of square almost an inch. Thanks in advance

You'd be better off getting the frame straightened by a pro at a collision/body shop, on a frame machine.
Proper frame anchoring and controlled pulling correction and dimension measuring verification
by a seasoned pro collision tech on a frame machine is well worth the cost.

Do it right the first time and you will only have to do it once.

You wil spend/waste more time and money on floor anchors and stands and pull equipment and
measuring equipment etc etc than the collision shop cost to
correct the frame on a collision frame rack.

I absolutely believe that you would be better off with a body shop and a frame machine. They will get it straighter then Ford originally built it without crushing or distorting frame rails. Some of their equipment can exert a great many TONS(10, 20 etc) of pulling or pushing force with the right adapters to prevent unnecessary tweaks. If you can find an old time body shop that worked with cars with real channel frames, all that much better.

The thing I question is if it is bent at the firewall,wouldn't you want to graft a undated front section on it anyways if not for nothing better braking??.

You first have to correct the "cowl sag" in the frame. Or your grafted frame will be bent too.

In collision-frame repair you always correct the frame before cutting and welding or replacement.

Get it straight first, then do what ever you want.

This is a easy correction on a frame machine, by a experienced bodyman.

Guys you know you can buy a new set of reproduction 34 rails for reasonable. Replace the rails and you have a frame straight from the get go..

What you have is severely tweaked but you do have a lot of good stuff there..I would turn the job down if it came my way to straighten..new set of rails is the way to go on that deal...

+1 on using a pro with a frame machine......but I also would go with new straight rails, cut and weld back in the cross members and such....make a jig or straight table to clamp the frame rails to and line everything up.....

The new frame rails are drilled for all the stock parts including body mounts and such as they are intended for the fellow doing a restoration to original...So all you do is cut the rivets holding the old cross members and reuse those in the new rails. you may need to modify the center X member for mounts if you are building a hot rod. You will most likely split the wishbones to allow for the installation of a late model engine and trans..On the rear you will do that as well to allow for an open driveshaft and you will need to make locating arms for the rear.

Here are some images of 34 Ford hot rod chassis..Yours when complete will resemble some of these..

Any more questions just ask...

I had a chance to work on it today I have it pretty close. Side to side is level and measurements are within a 16th. The frame rail is still pushed out on top a little cause it was smashed. Hopefully I can get it straightened out, its getting there.
