The alignment specs for the unibody should be available from a good collision shop.
Here's another

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
