Smitty
1/2 ton status
I'm trying to find the brake code for a 1986 CUCV (M1008, M1010, M1028, or M1031). I tried the Chevrolet dealer and he's guessing at JB8, but his system doesn't go back that far for decoding the VIN. The build sheet in the glove box doesn't list the brake system. I'm leaning toward the JB8 code too, but would hate to order the wrong parts.
