wtb 1999 silverado bumper, roll pan, subs

[silverado916]

im looking to buy a bumper to paint for my 1999 silverado, perhaps a ss front bumper that will fit? also interested in a steel roll pan since im going to have it welded and other custom parts at a good price. in the middle of customizing my truck so any custom useful parts are nice. also a custom box to fit under the backseat. would be better if it came with the subs and amp as well. let me know! thanks
