Looking for turbo "clamps"

I'm trying to locate a pair of "clamps" that hold the turbo compressor housing to the exhaust manifold, I've had to remove my turbo and the bolts are well seized - took a hacksaw to them but looks like it needs a grinder to finish it off, and the clamps will probably be past their best!

They look similar to this I think - but I'm not sure if that one will fit - can anyone confirm the model number of the Turbo?

I've seen them as part of a rebuild kit, but as far as I know my turbo is OK, so don't want to spend out! Should I just take a risk and buy the ones above?

Cheers
