Oil pressure line bracket bolt

[Kurt France]

I cannot find the bolt for the oil line pressure bracket bolt for my 70 BB. Does anyone have the info for this bolt, thread, headmark etc that I can use to identify it? Does anyone know where I might be able to find one. I have tried Paragon and the Doc. I have the bracket.

Thanks
Kurt

The screw in question is a 1/4"-20 X 7/16". It is indented hex head with a captive external tooth star washer. Common headmarkings were "E", "L" or "EL".

Finding these screws is no problem, at all. They are the same ones used for oil pan, front cover, and clutch cover on MILLIONS of Chevrolet V-8s in the 60's, 70's and 80's. Paragon carries this screw under their number 1850; they reproduce it with the "L" headmark. They might not know that this is the screw used for the big block oil pressure line bracket, but it IS the screw used for the big block oil pressure line gasket. I don't know if they sell this screw by "onsies-amd-twosies", though. They might only be available as a set for oil pan/front cover applications.

Thank you Joe, that is great news! I happen to have a few brand new ones lying around...somewhere.
