I have an O-320 A2A engine on my plane.

I need to replace a bolt that holds the engine balling to the cylinder head.

It's a Grade 5, 1/4-20 X 1-1/4" FULLY THREADED hex head bolt.

I haven't found where to acquire this bolt in quantities of less than 50 (I need one).

I have an engine shop here at C77, but they couldn't help me.

Does anyone know where I can find this bolt or at least provide a part number that the engine shop might be able to reference?

Thanks,
Glenn


PS - BTW, The reason such a long fastener is needed is because there is a baffling brace attached and secured via hex nut to the tail end of the bolt.
