rocker arm adjuster

Lardyfella · #1 (**permalink**) 04-01-2015, 06:27 AM

Guys I am stuck, I was changing the intake manifold gasket on my cobra and found that the adjuster on one of the rockers had sheared off. The problem is I do not know where I can get another as I am also not sure who made the rockers. I am guessing at Blue Thunder but they don't look the same as the ones online.

The nut is 12 point and is a 7/16 - 20 ARP, The stud has a recess with an oil gallery drilled into it that lubricates the push-rod tip, it measures 1.142" long with a domed recess that locates onto the push-rod.

Can anyone out the identify the rocker manufacturer and give me an avenue to get a replacement adjuster and nut?

The engines a big block FE 496 Shelby America block.

I wonder what caused the failure?

Should the pin be sticking out on the other rocker?

cheers
