Yup, the bracing should have been installed, but it wasn't......

Got in on one of these deals awhile back where someone else started a chop project, sold it, then we had to straighten the mess up for the new owner.....

First question--Do you have or have access to a laser level????? Makes it a bit easier. You've got to establish a centerline running lengthwise through the car....Mark this centerline on the trans tunnel with a center punch hole. No laer? Then find the center on the tunnel as measured between the door jambs. From this point, set your windshield pillars an equal distance from center and brace it up.

Mark this centerline further towards the rear of the car on the tunnel to a point between the rear door pillars. Set them straight and tack some braces in place.

Now, measure the X distance between the left windshield pillar and the rear door post for the right door, then measure the other X distance between the right windshield pillar and the rear door post for the left door. Make these distances match, cross brace between the rear door posts, and continue the same method working rearward on the car, establishing X Points, and making the distance equal.....

With a laser level you can set your centerline with a vertical beam all the way down the tunnel, scratch this line into the car, and measure everything off of it.

It takes a bunch of measuring, but the car can be saved...

Or, just eyeball it into place and weld it all together. When it's done and the doors won't open and close and the car isn't even close to straight down the sides, you can just tell everyone it's a Rat Rod and it's supposed to be that way!!!!

Hopefully, you'll take the time to do it correctly and not just use "rat rod" as an excuse for not having the patience to build a decent, straight car........
