Hoping someone can help me with this tag. I know most of what it means
u1=ordered this way
w6=??

AB41=318
C1=3 speed manual
R1=2 watt radio

SO Number
11009018 Has no letter to identify month

Body
WH23 = Coronet 2 door Hardtop

Trim
H=???
4=Bench seat
W= white

Paint
W=White
P=Bright Red
2=2 colour

W=white

Thanks for your help.

w/6= New car service with 5 gallons of gas.

The first three digits of the SO number is the SPD. 110= January 10th (1966)
the rest, 09018, is the remainder of Sales Order Number

H??= High Trim level.

The first letter in the trim code refers to the "Trim Grade". H = High

It looks like u1 = Sold Car / Expidite and w6 = New car service with 5 gallons of gas
