1960 Parking Lamp Housings

[Joe M.]

I removed both housings last night from body and recorded the following GM part numbers, 5948880 and 5948879. Neither part number matches the six digit part numbers in the 1960 A.I.M. Anyone know what year is associated with the housing numbers I discovered?

The front of each glass lens shows F-57. Is that appropriate for 1960?

Joe -

I expect that the numbers you found on the housings are the casting numbers for the die-cast housing; the part number in the A.I.M. is for the complete lamp assembly. The F-57 is the date that lens design was certified to the SAE photometric requirements; the same lens design was commonly used for many model years, sometimes on different/multiple car lines.

Thanks John for the insight. I noticed the same thing when I removed the license plate lamp covers, the casting numbers were not the same as the AIM numbers. These parts have to be original to my car.
