W204 driver seat issue

Oh well I never have such a bad luck on my wife 2010 C350 4M W204.

To make this short the driver seat caught a duster and I took the seat cushion off.

And notice that the short cable around 63cm was twisted and broken. MS said it cost $ 3,000.00 for the whole base and that what they sell no kidding ..lol I go to aliexpress and see they selling that cable around $ 10.00 CDN to my door. I see a Taiwan company selling that too but ask for $ 70.00 US same thing.

My question to you Sir there are 4 bolts on the rail to whole the motor in place and are they Torx bolts

my T30 looks too small. And do you Sir know what size was that ?

And on the short cable side there are 2 pieces of rubber holding the motor

one was twist and broken. Since MB only selling the whole frame. And I don't see they will sell just that piece of rubber. Well I can put some cable ties or Zip ties to hold the motor down.

I would like to know the Torx bolts size if you Sir know.

Thanks !
