Front timing cover reseal
So my 2016 SL400 front timing cover is leaking. I know there are probably thousands of threads on this but I am having a hard time piecing together all the info.
1) anything else I should do while I am doing this?
2) what are the part numbers for the single use aluminum bolts and where to buy them? I am seeing part number ba05.30-p-1003-01W in my ancient WIS/ASRA but I cannot seem to find that part.
3) I am planning to use Permatex Ultra Grey RTV. Is this a good choice?
4) Any other supplies I will need for this job?
3) Any tips/gotchas to look out for?

I have WIS. Where in WIS would I find the part number for the bolts?
All I seem to see is the special loctite gasket/seal remover product, the special loctite parts cleaner product, and the special Mercedes sealant called out.
