Who makes the engine in that? I have a diesel and that is a Perkins. 
I think I would try to get it at NAPA, or some place like that. The price seems awfully high. I remember the old chevys' being about 6 bucks... am I dating myself? <!-- s:wink: --><img src="{SMILIES_PATH}/icon_wink.gif" alt=":wink:" title="Wink" /><!-- s:wink: -->  Take the old one with you and maybe they can match it up with something. Just my 2 cents.
