Starter Shield Hex Head ID

[Mr70]

Need confirmation on the size of this Starter heatshield Hex Head,is 5/16-18 X 5/8 what was used originally?

Cannot find a good pic of it but it looks like a corner oil pan bolt??
The tube nut is not on rear solenoid screw, but we have it.
Did not take bolt out to check but it has a lip like pan corner bolts.

Shows as part number 9419370.

Punch that number into epay and you will get multiple choices.

Your size is probably right and these "assembly line correct" offerings have a lip like hers.

Cannot verify the head marking as her car is still put away.

Geralds Lemans blue brush paint job on motor- bellhousing sure is catchy!?!

Thanks guys,but still looking for exact dimensions if possible.

Another look at a 1970 [according to ad].
Sure looks to be 5/8" to me.
Has lip also.

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

Thanks, Greg, for making this clearer.
