stock but i want to put a air intake and headers

i want to get at least a 3 inch lift

i don�t know what im going to with the rusty bed im thinking diamond plate but that would add a lot of weight
i cut out rust and put sheet metal behind the hole and welded it on next i have to bondo it and prime it

i put a new head unit in and i have 6 speakers and a 6 cd changer i want to get a 8 inch subwoofer
i want to take that off and put diamond plate

I painted the underneath with rust-olium so that it prevents further rusting.

i put dual pipes and a high flow muffler
