I’ve got a project right now that could use some expert assistance.

This absolute basket case of a 1964 E-Type needs some serious panel replacement, but to make sure that everything lines up, I need more dimensions than I can currently find (I’ve searched this forum and the wider Internet and only found the images below.)
Someone referred to a “Knowledge Base” that includes Series I chassis dimensions? Can anyone point me in the right direction?



These get me started for sure, with some good measurements from datum (which I assume is the floor) point or the zero plane.
Anyone got more? Does anyone recognize where these pages are from? (They’re numbered Pages 26-28, I assume there’s more somewhere.)
