Have done over 60 of these bumpers and have a really good fixture for them. I offer this service for 465. This includes return shipping to you.
What I offer is I take your core bumper. Fixture it, cut the opening, tack weld the mouth in, weld and cool the bumper during the process, grind, blend and send back to for either chroming or painting. I do NOT offer chroming.
