anti roll bar replacement - what bolts do I need?

[perfection]

I'm going to try and replace my anti roll bar this weekend which involves dropping the subframe. I want to replace the stretch bolts and do it by the book.

It's the fwd version.

I'm looking at the workshop guide here and trying to understand what bolts I need to replace.

Seems like I'm removing the 4 bolts that hold the subframe to the car and loosening 2 more (as well as removing/replacing the arb bolts).

I can't seem to find part number for the 4 bolts which would be bolts 1, 8, 9 and 18 in this picture:

This is the parts catalog I'm using: wishbone; wheel bearing housing; anti-roll bar Audi A3/S3/Sportb./Lim./qu (A3) 2008 year Audi EUROPA 407000

but bolt 24 in the below picture doesn't have a part number associated and there doesn't seem to be anything for the other bolts (9 & 18)

I seem to be going round in circles. Normally I find it quite easy to get part numbers and find the bolts I need.

So any advice on how to actually get the part numbers for those 4 bolts would be good. Guide also says to loosen the 2 rear bolts on the subframe assembly - would they need replacing too?

I believe the ARB bolts are 4x N91073401 - M8x75 and have found a set on ebay for a tenner (yikes).

This can be a bit confusing on the PQ35 platform but as to which bolts need replacing the answer is every single one you remove. To help us in this situation we pre order in the bolts we THINK we will need but keep a huge stock of other as backup as this problem can cost us £66 an hour in dead lift time.
