Looks like most of the info is right there, plus a straight unibody. Build the base to size, then slap it under a straight unibody and fab up to the frame rails, spring and K member points and maybe even the door hinge points. You could probably make the frame supports on a complete car except the areas above the rear springs, but could still take measurements. If the drain holes are standard (they should be, they are used in the alignment drawings), you can put tapered pins on the tops so they self-align. Firuge out what hard points are important and build removable arms to define them. The alignment specs for the unibody should be available from a good collision shop.

The "unibody" specs you refer to above is a little misleading.
There are no above the frame, "unibody" specs for old mopars... There are only below the frame specs..
There is only 1 reliable source for those, the old tru-way frame book.
There is a page in the 196X or 197X book for your specific mopar. This page shows all the point to point specs to within a 1/4 inch and it shows the datum line...
There is no point of reference, or spec, for any above the frame measurement.
Modern collision shops do not have frame specs for cars that old because they won't touch an old car (which needs structural work anyway) with a 10 foot pole.
There is a guy I believe you can call, give your car/model year be sure to mention convertible and I believe he will fax you a copy from the book.... (for free!) at least he has done this in the past... I forget his name I'm sorry...
Here is the link: http://www.klinesauto.com/PDFs/Current%20Newsletter%20PDF/Frame%20Spec%20Library.pdf
There are 5 or 6 locations shown. I forget exactly which one it is (try Reading or Pottstown first) Ask about the tru-way frame books. Tell him you year/make/model etc...
Best of luck to you

I spoke to Craig Hopkins (AMD installation center) about this very thing last year. He said when they first built their jig they did this. Problems arose when they realized the holes weren't always in exactly the same spot between models and/or aftermarket frame rails. His advice was to tack weld the supports to the frame and cut them loose when you are done and skip the locating pins altogether.
I also spoke to AMD directly and they suggested to support the car at 8 points. Of course, I was talking about a convertible, but I don't think too much support can hurt you.

how about no way,no how?
just for instance 68,69,70 bbody the holes are different for each year. i didn't even get to the dodge/plymouth differences in the same year yet
amd saying that about rails shows they don't know squat about replacing mopar metal why would they even try it to begin with??? they must be learning on the job! (any mopar body guy should know about the rail difference),they should just stick to making it unless you plan on doing metal replacement for a living, a jig is a wee bit overkill i would say

Awesome stuff guys! I cant believe I just found this post as I have been thinking about building a frame/alignment jig myself. Matter of fact when I was at the Nats and saw that Autotwirler was selling one. It was very pricey. I tried twice to talk to the sales guy but each time he was busy when some other yahoo shooting the breeze. I just didnt want to stand around forever, so I left. Here's the link. http://www.autotwirler.us/product-p/abt.htmIm trying to decide how best to build mine. Do you guys plan on putting on those leveling/stop/pads shown on the AMD one? If so, where can they be purchased at. I would also like to know how you came up with your measurements, or did you use the dimensions from that frame sheet to use to cut the stands (or have you not gotten to that yet)?

I scarfed them off of some equipment in work headed for the scrap pile, but they are available commercially : http://www.carrlane.com/Catalog/index.cf...A3C3B285350415FAlthough mine isn't quite finished in the picture, I made it (if I remember) 36" to the center of the rails. Thought being, it splits the difference of how the frame rails vary in width on the car. I then made the uprights mimic the frame dimensions in the above post. Jeff @ 521Restorations has a nice write up on his as well. http://www.521restorations.com/index.pl?page=framejig

Here is how I mount the car to the jig. The bolts go into the factory holes and mount and un-mount quickly and cleanly.
