Drew, Chris and all:
Going over some production numbers and order forms for the 1972 LeMans, trying to put the Y99 handling package and G60 tire questions more into perspective.
Production numbers:
G60 tires were installed on a total of 1,708 '72 LeMans. I assume that this number would include WW5, WW4, Y99 and those cars with just the G60 tire option. From what I see on the order form, one could NOT order the G60 tires as a separate item EXCEPT on a GTO optioned car.
The Y99 Handling Package was installed on a total of 1194 '72 LeMans. I assume that this number would include the WW5 and WW4 optioned cars.
The WW4 option package was installed on a total of 125 '72 LeMans. The WW4 package could be ordered on any '72 LeMans coupe or hardtop. No 'verts.
The WW5 option package was installed on a total of 290 '72 LeMans. The WW5 package could only be ordered along with the W62 GTO option.
So . . . it would appear that 514 '72 GTOs were equipped with G60 tires but NOT WW5 or Y99 equipped.
Does this make any sense? My head hurts . . .
