I had the MPC open . . .
If you are referring to the lever (which includes the pin).
it's a "2A637-8 Lever Parking Brake Cable to Secondary Brake Shoe".
Looks like I6 and V8 are the same but they are different by drum sizes.
10" brakes are C9ZZ-2A637-A / C9ZZ-2A638-A (RH/LH)
9" brakes are C9ZZ-2A637-B / C9ZZ-2A638-B (RH/LH)
A length of the item might help here.
