On the 392 they just support the plastic covers 

[Katfish]

Well that's interesting, thx for the reply.
It seems like they have a small hole in them, so that threw me off.
Glad it's not something else I need to figure out how to hook up.

The struggle continues.............

Yeah, just for an engine cover. Probably could be removed, if not using.

[Katfish]

Yeah, I don't like the look with the cover.
I'll leave the studs on, then probably eventually trim them off later when I'm sure.
