Part numbers required, 172 dogbone mount and manifold to Cat' bolts

[len_beach]

As above, I know the dog bone mount is a fairly common request but the forum crashes every time I use search.

I also need the manifold to Cat fixing bolts/kit part number as mine is rattling like a bar steward.

can these parts be bought from GSF or are they dealer only? Any rough costs would also be appreciated.
