When replacing the heat exchanger or the exhaust pipe, the mounting materials can in most cases no longer be reused.
Sealing rings must always be replaced, as they are single-use. But also brackets, nuts and bolts are often no longer worth mounting.
The assembly mentioned here includes all parts necessary to mount the heat exchanger on the exhaust and/or the exhaust pipe on the exhaust and applies only to type 1 engines.
With one set, it is even possible to choose between a standard mounting set (galvanized steel) or a stainless steel version.
With this latter set, you are forever safe from rust. If you have purchased a stainless steel exhaust, heat exchanger replacements and/or exhaust pipes, or are planning to do so, also take the stainless steel mounting kit, otherwise you will always have rust and that is precisely why a stainless steel exhaust system is designed.
Look at the "alternatives" tab to see if the mounting kit is available in standard steel or stainless steel
