I need timing cover bolts, no idea what happened to the old ones.. anybody know what size bolts I need?

Probably 1/4" x about 3/4" long NC. I don't like generic bolts on the timing cover. The 7/16" head is big. Late model or aftermarket bolts use a flanged head so the same size bolt only needs a 3/8" socket. I just went and scrounged a bunch from the junkyard the last time I needed some.

1/4 x 20 x 1/2 i think????

Old thread, but... same problem here. My screws are rusted pretty bad. Any source where I can buy them new? I also need oil pan bolts and thermostat housing bolts...
Thanks.

Awesome! Thank you!
