C2 Heater Hose Bracket Bolt, 9411890?

[Alan Drake]

Mar 64 FI car;

About to put the heater hoses back on car.

The alternator is secured to a support which bolts to the exhaust manifold. A clip (3828920) is then secured to that alternator support bracket with screw 9411890, to keep the hoses away from exhaust manifold.

The Problem is - looking at the AIM (page D64) the clip should be attached to the bracket by screw in the second hole of the support bracket. However that hole and the next one to it are not threaded.

Ques; What is the size of the screw, 9411890! (Will tap hole for correct screw and order one)

Now the clip was on the car in 1970 when I installed headers, but how was it attached??? Is the AIM missing something? Just another deviation from the mfg line!

Thanks
Alan

GM #9411890 was a 1/4-20 X 5/8", hex head tapping screw which was zinc or cadmium finished.
