Thanks for the engine clarification, mockingbird812. This one must have had the 350 hp L34. That's neat that your wife lived around here... we're right on the border of Westmoreland and Allegheny county, near the 286/380 junction. I'm actually a Pitt student and fight that Oakland/parkway traffic nearly every day. I'm on summer break now and I sure don't miss it!
mr70, I'll answer your questions on both forums so I get better coverage. The car was an automatic and purchased from Bauman Chevrolet in Wilkinsburg, PA. That dealership doesn't exist anymore but the main phone line now runs to Centennial Chevrolet. I called them a few days ago, but they denied ever having ties to Bauman, so I'm not sure what that means. The signing date on the quote/delivery slip was February 9, 1970 and the salesman was John Deveraux, Jr. I didn't know that about the paint naming differences, but the paper actually lists "special paint - Hugger Orange" under the Remarks section.
Thanks again for all of the help and interest. It really means a lot to me.
