Hi John,
"Leading Dimensions" is a technical drawing included in the original
BMC factory workshop manual (AKD 4884) and how size specifications
are referred to for British cars of that period (at least). Somewhere
I have a small version of it scanned. I suppose I should post it on
my "Tech Tips" page one of these days.
