Hey y’all, seems like this is the place to ask. I acquired a rear bumper that’s missing the top plate/step plate. Ordering the replacement part from ARB would cost a small fortune, so I want to fab one myself if I can. I’d like it to look similar to the one it came with originally, but I don’t know where to source the material, or what it’s called. Seems to be what door thresholds or stair treads are made of — it’s a sheet metal with ridges for tread. Any idea where to looK for this, or any other advice? All ideas are welcome.
