Hi,
The terms (Mk2) 'A' & 'B' were not used in period. They have been adopted by various writers & replica manufacturers to give a quick way of describing '1966 spec' or '1967 spec'.
There are many differences between the '66 & '67 Mk2s, those that come to mind easily include,
Front mounted spare wheel '66 / rear mounted '67
Twin luggage boxes '66 / single '67
Single carb. '66 / twin carbs '67
Passenger door cut just above the side window with roof piece fixed to the main roof on '67
Roll cage fitted for '67
Front mounted oil tank '66 / rear on '67
Front body cut away below grille opening on '67
etc...
Then factor in the differences between the Shelby, Holman Moody & Alan Mann prepared cars !
ie. The Shelby cars for 1966 had a divider in the hood opening, the Holman Moody cars don't.
Also bare in mind that some cars such as 1016 had lives after Le Mans '66, repainted & updated to 1967 'B' specification.
For instance although 1016 is beautifully & sympathetically restored and returned to its 1966 'A' colour, if you look at it today you will see a combination of 1966 'A' and 1967 'B' features, (such as the 1967 dashboard, etc).
