I have a 65 fastback that had the front-end wrecked in the early 80's before I bought it. I came to realize it had a poorly done restoration, so around '92 I removed the engine bay sheet metal, had the frame straightened at a local shop and new sheet metal welded in. The frame has been in storage and I just recently restarted work on it. I've tried to add several aftermarket products in the engine area and nothing was fitting. All the issues seemed to suggest that the engine bay was too narrow. I found the Liskey drawing and my car measurements were dead-on with the drawing. However, the frame rails still didn't look right - they seemed to have an hourglass shape narrowed at the shock towers. My lower control arm mounting bolt holes were 21.5" center-to-center (Item "G" in the Liskey drawing). I then found another copy of the Liskey drawing with different hand-drawn dimensions added in. In this drawing, the lower control arm hole dimension was 22.25". I took the car to another frame shop in town where the diagnosis was that the rails were still bent. They had the book of Liskey drawings, but said regardless of the specs, the frame rails were not straight. I had the frame straightened and lo and behold, the dimension needed to get the rails straight was indeed 22.25". Now all the equipment fits in the car and the alignment is coming out fine. I can't vouch for the source or accuracy of the hand-drawn dimensions , but I thought I'd share this with you since it worked for me.
