88-98 Stepside bed replacement parts

[iDriveGM]

I have a 95 chevy ect cab stepside and the box took a bit of a hit. The bottom of the rear passenger side got hit and broke off. Does anyone sell replacement sides for this box? Also when i took the box off i found the crossmember on the front of the box thast bolts to the frame is rusted out, can i buy new ones or should i just fab one up?

We just got 2 new boxsides from GM for my dad's 88 stepside. I couldn't get them here in Canada but we got them from a dealership in New York. They are pretty pricey, regular was 900 bucks for each side, you might be better finding a new box.
