E63AMG2009

I bought an 09 E63 and the auction and the factory bumper was destroyed. I bought one from Aeuroplug and there is no conceivable way to mount the parking sensors in the back of the bumper. Spokane MB dealer said the tangs should be built into the back of the bumper? I do see squares in the back of the Taiwan product molding where it looks like some sort of adhesive backed sensor bracket maybe could mount? These say they don't fit and are on perpetual back order..... 1718850014 https://www.ecstuning.com/b-genuine-...et/1718850014/

I'm really in a bad spot here. Aeuroplug has been a disaster since day one.
