1969 Z/28 Parts needed.

[gelpro]

Hello everybody. My name is Dan and I am a new member of this site. I own Gelpro Rod & Muscle in central Missouri. We build Street Rods and Muscle cars and fabricate most anything. I am also a 1978 graduate of Wyoming Tech.
Im presently finishing up a '69 Camaro Z/28 and am short a few engine parts to make the car all match up.
I need a correct date coded long water pump (early '69 Jan, Feb, or March)
I keep watching eBay for one but no luck yet. Anyone have any ideas where I can come up with one? Thanks for any help and I look forward to viewing the web site.
