According to my 1966 AIM and my 1966 Chevrolet Parts Catalog (effective Oct. 1965) the part number for the "early" 1966 grill supports is 3875777. According to the revision record in the AIM GM # 3875777 was replaced with GM # 3897389 on 12/03/1965. Enclosed is a couple of photos of a pair of NOS 3897389 supports that are stamped with the letter "W" (the manufacturer, I assume). I removed the white GM part number stickers to clean off a few areas of very mild light surface rust.
Two questions:
1. What is the difference between the 3875777 and 3897389 supports?
2. What are others doing to keep NOS supports from rusting? Before I installed NOS supports on my NOS 66-67 grill with 4 NOS 9418482 rivets during my 1966 restoration (1980 to 1995) I painted the supports with a "natural metal" paint.
