These are not codes from an f-body, but with the ample resources here, someone should be able to find out what these are.

FKZ
FK3
L84

SLL
XEB
YD3
YD5
YEB
ZEB
ZK5

ZM6
ZM7
ZY1
Z53

7CA
74E

Also, 5Z7 refers to a GM T&B. Anyone know what this is?

 

If no one can help directly, does anyone know of other GM non f-body specific websites they can point me too? Thanks.

 

B32 - Covering Frt, Floor Mats, Aux
FK3 - Arm, Tors Bar Spring Adj (B)

OK The L84 is definitely wrong. I am pretty positive that stands for a 4.3L V6 with CFI, which is what the vehicle came with.
