This is all good information.
I have a question about bolts. What kind of finish was applied at the factory to prevent rusting? When I repainted my shroud in front of the radiator, I carefully wire brushed the bolts. Now they are rusting, as I must have removed the protective coating. Do they need to be re-plated?
It takes a bit of digging,but the answer can be found in the parts book.
Packard calls the shroud a splasher and it is listed under Group 30.87498 in the 1948-54 parts list. The fasteners are also listed in this parts group, in this case the screws for all 22nd & 23rd Series are part # 394575.
The index at the back of the parts book for # 394575 shows other parts groups where this screw is used and also a Utility Parts Group number 50.003
The Utility section of the parts list is now available on this site and by looking through Group 50.003 for hex head machine screws the description for # 394575 is found as 1/4-20 x 1/2 w/washer, cad
The description translates as a hex head machine screw, size 1/4" with 20 threads per inch, length 1/2" with an integral washer and cadmium plated.
So cadmium plating or a finish such as the Eastwood cadmium paint would be appropriate for these fasteners.
