Thanks! I have been collecting any measurements I can find. The more to cross reference the better!

I wasn't.... At first lol. It just got to the point where I didn't like some of the metal work done a long time ago and the shape of the shock towers and frame rails. Yes, I could have fixed everything and I seen others fix them up by patching, but I didn't trust my skills to do that and decided to get new metal. Anyways, we finally figured out what we had going on with being out of square. I don't know how we did it but when we measured and welded the frame rail into the passenger floor support it was in too deep. We decided it was easier to cut it loose from the transmission crossmember than cut the floor support from the frame rail. This will mean we can't use the floor support for any future measurements unfortunately. But everything is square now and the torque boxes are in. I will get a picture and post updates in my build thread probably. Hoping to make some good progress today! Thanks for the help!

I put in some threaded rod. Got the frame rails spacing right, then found that it was out of square somewhere. Just finished cutting the welds from the passenger floor support to transmission crossmember to move that side. We are currently remeasuring the car to the datum line, checking for square, then going to try tacking some things together. Finally I think we are going to fit the doors and fenders somehow to see how gaps are.

Ok. I really need to stop over thinking this stuff. Thanks! Edit: Should I worry about the spacing at the top of the frame rails much?

Hey all, Slow progress on my car but I am getting ready to weld in torque boxes and on the passenger side I have a gap of 1/4" or so. Everything seems to be measuring out fine so I am not sure where the issue is. I put in an inner rocker patch that is homemade so ignore how much that sticks out. Some additional info: the space between the top of the frame rails is 27 3/8". The bottom is 27 9/16". That would probably fix the gap to spread them apart. But the rails are sitting Plum or extremely close to it according to my angle finder. Maybe 1° off.

Can't wait to see this come together.

Thanks! I am just getting back to my car after not working on anything all winter and this will be very helpful!

Yes. Was trying to get as close to the center of the hole as possible. I also thought the bottom of the floor support should be level. It is possible it is sagging but it is about 1/2" lower at the rear of it than at the front. That seems excessive. Just trying to figure out where to set the new drivers side floor support. I don't know if I should set it level or try to match the passenger side. Does anyone have measurements from the bottom of their floor supports while the car is setup like the diagram with a datum/baseline?

Ok. After a lot of fiddling I have the passenger side X-6 as close as I can get it and also the X-6 1/2 measurement. When these two locations are set I get 12 1/4" at "B" and 12 11/16" at "A". I am guessing this is because of a little bit of sagging in the front end. My next question is that with these locations set according to the diagram I have found that the floor support is not level. Should it be?

I actually have something like that already too which I used for my siding. This gives me a good excuse to get a shiny new laser level though. :)

I have the drivers rear fender apron removed and then the lower portion of that frame rail, torque box, and floor support. Right now I am just trying to set the car to a known position so that I have something to go off of in order to start welding in new metal. Originally I thought it would be good to level the car at the rockers and that the floor supports and bottom rear of the front frame rails would also be level but now realize my error. It just seemed logical to me that the rockers would be parallel to the datum line but definitely found out that is not the case. I think I am going to go buy a better self leveling laser level so that I can set it in one spot and leave it. I am also going to remove the rear axle and leaf springs I think so that they are not in the way. There is some patch metal at the rear shackle of the passenger side so it is tough to get that measurement. Thanks everyone for the help!

I think it is pretty level. I only have a 4 foot level but everywhere I have checked so far has been level. I think what I will do when I go back out to work on this today is measure down to the floor from my laser line at several locations just to be sure.

Thanks again. I never even thought about the fact that the drawing does not show the rocker panels. I just assumed those would be level with the frame rails. I am getting closer now. Hope to finish leveling it tomorrow and then maybe I can start welding in new metal.

I think you nailed it! I found my old cheap laser level and put it at the X-6 for a datum line. Instead of 11 3/16" I got 15 5"16. I am going to lower the rear of my car the 4 1/8" and see how things look.

Yes, my car is the opposite though. Right now my "A" measurement is 21". My "B" measurement is 21 and 7/16".
