Beware of Classic_Specialties they will not work with you if the part is not as described. I bought a fuel sending unit seal kit decribed to fit a 61 Olds it wasn't for a 61 Olds. Seller makes it out to be your fault and is abusive in replies. Here's a link to the same part he is selling as a part to fit a 61 Olds.
