Maybe this helps:
This is the code for the square gasket between the manifold and the turbo: 5521445;
And this is the code for the gasket between the turbo and exhaust 51814387 ~ 27 GBP.
You should change the gasket for the bottom oil feed as well mate, they are only about £3.
Don't suppose you want to sell me your VL37? .
However fiat wanted £67 for the lot... I have tried another way to get these gaskets cheaper (I know expense shouldn't matter when it comes to something like gaskets; but they will still be OEM quality) and I will let you know if it has worked when they arrive!
Did they arrive and work?? If so where from matey? Cheers.
