Hi, I recently ran across some NOS parts that I don't need. I have been saving parts for 24+ years, any help would be appreciaited. I believe these are Camaro, Chevelle. so I need what cars and years these are applicable to so I can sell them here. I don't necessarily trust the tags on these parts.

1) NOS Temperature Sending Unit for Gauges ( tag says 66-70 Chevelle,Camaro,Z28,COPO) GM#1513462 GR.1.150 The AC Delco and 12V are embossed UPSIDE DOWN- correct.

2)NOS Vacuum Advance Delco #D-1328 On unit - MS 163 16
tag says 67-70 Camaro,Chevelle,Nova w/396 69 COPO,Z28,70 LT1, 350

3) NOS NIB Trunk Latch. note Pontiac P/N GM #753019 GR 12.342 -I don't know if Chevrolet used the same P/N? but, have seen these on eBay that mentions it is factory correct for some Chevys. Tag 66-70?

I need help so some one can use these parts, they are mint!! Larry B.
