Warning! Don't accuse me of being totally anal and long winded, but I have inventoried every single attribute of every single fastener on my car, so I can get them batch restored and get them each back where they belong.

On my 69 340, both coil mount bolts are 5/16-18 x 5/8 with 5/8 OD captive conical washer, grade 5.1.

One has head marking of 3 dots and is S2 finish, phosphate and oil.

The other has head marking GL and is S36 finish, zinc dichromate, yellow-rainbow.

These are the same as the photo of part B-12548, "Chrysler Auto Trans Pan", on page 101 except for the head markings and S36 finish here:

The GL head marking is shown on the inside front cover, and the grade 5.1 head marking is shown on page 2 here:

Sorry to say I did not take note of which bolt went in which hole, but I could have switched the bolts years ago anyway.

Scott, tell me which bolt goes where, and I'll take photos as soon as I can get back to my Mopar man cave.
