Hello I need an answer on Mercedes eaton type superchargers. Hope that a knowledgeable person can help me!

I am working on a twin charge project and need the Eaton M45 size supercharger. I also require an electric clutch with a small as possible pulley.

Regarding superchargers on smaller Mercedes engines, it looks like m45 and m62 sizes are used. One of the larger appears to have an electric clutch as well.

Here are a two links from current e-bay items.

On the second I have seen people call these m45s and m62s. Can somebody tell me which are which?

Which Mercedes model uses the M45 size, and do any m45s come with electric clutch?

Thanks for the help!!! If I can get an m45 with electric clutch, that will save me some fabrication!
