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".

I am doing the drivers side, just more metal. I am guessing the bottom of the frame rail and the floor support that goes on next should be level when the rocker panels are level. I am trying to figure this all out because if those pieces are supposed to be level, then the frame dimensions in the drawing above would not make sense. I would have to bring the front of the frame rails at the front cross member would need to come up almost 3/4". Doing this would make the bottom of the frame rail and floor support not level in my opinion.

Yep. That is where I was measuring. I have done it from the top and the bottom.

Hoping that we can have a discussion about front frame rails. I am working on my 1969 Coupe and at the moment getting ready to weld in a front frame rail patch, the floor support and torque box. According to the frame dimension picture that has been posted many times the front of the front frame rail measurement "A" should be a quarter inch higher that the measurement "B" at the cross member support area. My "A" measurement is almost 1/2" lower than the "B" measurement. This is with the car level at the rocker panels. I have had a couple people tell me that the front frame rail does slope down. Those of you that have way more knowledge than me on this and have done several cars, what is correct? If the diagram is actually correct, how do I go about fixing this? The gaps for my doors and fenders did not seem to be that bad before disassembly but it is possible that it was worse than I remember. Calling @latoracing @mustangstofear @Ridge Runner Here is a link to the diagram again for easy reference.

That is what I was thinking too. Then I know it is going to be solid. Before I do anything else though I am still trying to get some type of confirmation if the front frame rails are supposed to be level when the car is level at the rocker panels. The front of my frame rails by the radiator brace are 1/2" lower than at the firewall. I am measuring to my floor and have checked my floor several times and that is level. Will probably check again for a sanity check though.

Thanks. I might touch base with him.
