Thanks, I will checkout demello too. I keep trying to contact bud built to ask but so far no luck. A while ago I asked Demello and they basically said they could not be sure but it seems they have done some GX470 bumpers etc since then so maybe they know now. I just still don't see the GX on their website for parts. Think I will avoid OPOR for now as I don't like they idea of rivnuts either, thanks for the heads up.
