Engine/Transmission (1994 - 1998) Lost allen plug on AFC

[GrantP]

As the title says, I've lost the allen plug that covers the "smoke screw" on the AFC. I apparently hadn't tightened it enough after adjusting it yesterday, I went back to make further adjustments this morning only to find the plug missing. Does anyone know where I can find a replacement? I don't even know what the thread size is to try to cobble up something... Thanks in advance.

I would try the local injection shop

The thread size is 18mm x 1. 5. I found an oil drain plug at the local auto parts store that will do the trick until I can find the original part.
