You could go to the Library section of this forum under "Mustang Hardware Spreadsheet 67-68" and open file "MHW67-68AP01.xls" scroll down to "Window" in the description and see part number, description, quantity, application (the "AP01" part of the file name with references to where the information came from. Where the information came from is the 1967 Mustang Body Assembly Manual (AM0016) and on pages 38 and 39 (spreadsheet references N7-8600-1, -2) you will find assembly procedures (Ford Engineering listed the item numbers by assembly order in most cases) and alignment procedures.
I strongly advise you to get a set for your car's year. At the least, a common reference drawing, right or wrong, is available.
