Mr70,

9419370 was a bit elusive in GM docs. I found a reference in the Parts and Illustration Catalog M-SB September 1987.

9424877 Bolt, Engine Oil Pan 5/16x18x3/4 300M STL *REPL 9411911, 9419370

The Oct 1969 P&A24 Lists the replaced part numbers as:

9424877 5/16-18 x 3/4 . 300M (300M = Chrome Nickel Steel)
9411911 5/16-18 x 3/4 . W/washer 280M (Lock Washer)

I hope this helps,

Greg
