I was not going to venture info, but I was just out in the garage getting soda and checked on the 94 (different plaque, but I am thinking they kept the same size shanks?). The 94 intake plaque uses a T20. Based on what Adam said, that might be the same size and work.89MustangGX said:I believe you are looking for a T20 sized bit. If not, it's a T15 I think.
