Lootha BPZ

KiraK. You asked for opinions. I believe other posters have pointed to good reference material. I believe the Pictured Z did start with correct 638 black pearl metallic paint. Due to the repaint however, I don't believe you will be able to prove it started with a dealer applied Sports Appearance Package without additional documentation. As the Z sits now, it's difficult to tell if the repaint is black pearl metallic or just black. Regardless as noted the stripes are incorrect. The sunshade appears to be correct based on the curvature of the blades and locking brackets. The dual racing mirrors appear correct. The part numbers are inside the base of the mirrors so bring tools if you plan to check. Rims as noted are incorrect. The five speed and AC are desirable, but other condition issues will be a restoration challenge.

KiraK. Your 12/77 chassis #441753 is fine for 1978 model. The 1978 models ranged from 8/77 through 6/78. I have a number of black pearls and one plate is very close to your picture. 12/77 #441559. If your able to post pictures of sunshade and mirrors I'm sure you will get good input to confirm if they are appropriate for the Pearl SAP
