Exhaust Heat Shield T4

Hello!
My old T4 2.5 TDI ACV had to go for its technical inspection (TÜV).

He wrote me a whole page .
Okay, I already knew that.

Replacing or patching thresholds is also included.

I've finished the chassis.

To reach the threshold, the exhaust had to be removed, as well as the front heat shield above it.

So far, I've exposed everything, and I'm sure I can handle it all.

But the heat shield is actually completely ruined.
So, there's nothing like that on eBay.
Not even used items.

I saw that there are apparently universal sheets available that you have to assemble yourself.

Has anyone had experience with that?
or what could I do?

Try using Google... it might not be cheap, but there are solutions available.
