ARB Front Bumper Install Question

Hey Guys - Looking for advice from other 2nd Gen owners that have installed an ARB front bumper.

My 2006 has some light frame damage on the front left corner of my tuck. Will this affect the install?

 

After searching around for a good bit I finally found out what this part is called "CROSSMEMBER SUB-ASSY, FRAME AUXILIARY": https://www.toyotapartsdeal.com/oem/toyota~crossmember~sub~assy~frame~auxiliary~51021-04010.html

It looks like it's welded to the frame. Has anyone ever replaced one of these before and know how to go about doing this? I'm thinking that I could get the ARB to fit but it may be nicer if I just replaced the entire part so it doesn't give me issues. Does anybody have experience with this?
