Need Part Number Help: 9419005

[Floyd B.]

I'm finalizing my shopping list for Carlisle. Somewhere along it's 46 year journey my car suffered a side-pipe conversion. I have an original rear valance panel but now need the bolts to install it. The two longer bolts that secure the center of the panel at both upper corners of the license plate area are identified in the AIM on page J131, UPC-1, Sheet F24. The part number is 9419005. This part comes up empty on the GM Parts Wiki and I can't find it in any of the other parts books that I have.

I need to know the dimensions, thread count and the expected head mark of this bolt.

Thanx

From what I can tell, the GM #9419005 may have been available in SERVICE but, if so, it's been at least 50 years since it was. However, it could well have been used in PRODUCTION long after that time.

The specs I can find are as follows:

1/4-20 thread size

7/8" length

phosphate finish.

I have no idea of headmarkings. Most likely, it could have been any period correct headmarking. A very common size bolt like this was probably manufactured by many.
