Technical Mounting for parabolic leaf spring

[Pesa]

Hi
My leafspring mountings to underbody is getting pretty rusty, so i doubt it will pass next MOT. I,m talkin about the steel "box" that is bolted to underbody & holds the leaf spring in place in front end of spring.
Can someone supply me w/ a partnumber for this. I have checked EPER but to no avail. Drawing have also been nice to have

The car is a Ducato Box 244 2006
VIN# ZFA24400007783371

Thanks
