Decode Steering Box Tag

Here is my crack at it:
HCC-AW is for a box that came on a car equipped with powersteering, same 16:1 ratio as GT manual box.

6B18C- a Feb. 18, 1966 assembly date, not sure about the C.(I think the rest is correct date)

1967 S code GT Deluxe Coupe 65B
1966 Convertible 76B 289 4 speed
1964 Fairlane 500 2DR HT-the new project
1986 Jeep Cherokee 4X4 the "beater"

The "C" tells it was manufactured in the third work shift of that day, i.e. 2-18-1966
