Title: Z28 thermostat housing
Post by: montgomg on January 12, 2010, 01:28:14 PM

I have an original thermostat housing (PN 3877660) for my 69 Z28.
I understand these to be date coded but do not find a date code on mine. I do find a 9 followed by the letter P inside a diamond.
Could someone shed some light on this. Thanks.

660's aren't date-coded; those are mold cavity numbers and supplier identification.
