Does anyone have frame dimensions for a 68 Mustang Convertible? I am doing a full replacement/restoration of the frame components and would like for reference and double checking.
Thanks

The Ford shop manual has the dimensions for the jigs.

Since I don't have the manuals, maybe someone out there would have them in electronic form?

Working forward the measurements at the center of the bows are :

20 1/2" from front edge of trim to middle of Bow #4 (~22 1/2" from upper edge of drip rail to center of Bow #4 if trim is off)

15 1/2" Middle of Bow #4 to middle of Bow #3

17 1/4" Middle of Bow #3 to middle of Bow #2

16 5/8" Middle of Bow #2 to back edge of Header

These probably vary slightly, they were taken from my '68 with the jigs in place for spacing, but on my top the alignment hole on the jig does not line up with the hole in the side rail for some reason. The Bow #4 dimension is correct, all top vendors I looked at use the 20 1/2". Bows 2 and 3 are based on the jig, the header kinda "floats" as there are no references I've seen...

You can just use tape to hold the bows in place while you install the side pads.

I am sorry, I may have confused the subject.
What I am in the process of doing is replacing the floors, torque boxes, front and rear frame rails and want everything to go in as close as I can to factory specifications.
Thanks

The Ford shop manual shows the basic dimensions and a diagonal measure. There is also a lot of info for cvs and strongly suggest that you buy one. Va. Mustang sells new ones, exact reprints, reasonably priced at 42.95. Also recommend a chassis assembly manual.

There are number of websites showing the work your car needs. For the rear frame, Hoosier Buddy did one in his cv. He may have pics. 68cvert has also done extensive work on his 68

Have done a few floor, inner rockers, torque box r&r's but not the complete front and rear frames. The better educated you get before starting, the better. That's a BIG project.

Thanks guys!

After I read your posts, I did some searching online and found a website: http://www.actionsalvage.com/manuals/ford.asp that has electronic versions of the manuals. Has anyone gotten these and are they any good/relatively easy to use? (word or pdf files) I think that I will definately get a set of hardcopy manuals, but also it might be nice to have them on the computer.
Any suggestions?
Thanks again!

That is a link to my site...and it is for a 68 Convertible, although that is only the frame specs. Some of the info HERE is from yelostang (Thanks SOOOO much Peter), some is from the Shop Manual...and the trunk specs were originally taken from my car before I replaced the rear sections of the rear rails. Hope they help.

I agree 100%. The task of the rebuild of my car does look quite formidable. I plan on sending the bare chassis off to the media blasters in the next couple months and I will take my time and be very careful with the measuring and positioning of all the underbody structure. I think I am up for the challenge. Has anyone out there made some sort of platform/jig to measure and mock their car up on? I was wondering if maybe building something out of 4x4 box tubing that will be leveled, take all the measurments from and build mounting points, as did Ford during production. Maybe a little too ambitious?
Any HELP and TIPS are GREATLY APPRECIATED!
Thanks
