Fitting kit for catalytic converter

[AndyPembs182]

I’m fitting a replacement catalytic converter on Saturday to my 182. Can anyone recommend a fitting kit? Which parts would it be sensible to get?

I didn't replace my cat, but I did have both sets of clamps replaced as they were pretty grotty, I went with this for the manifold side and this for the other side, I've got a Milltek cat-back with a standard cat for reference.
