u are going to have to get rid of ur abs, and have to go with a 7" brake booster, you will probably want to get rid of you air bag sensors on oyur radiator support to get rif of some wires,you will also want to extend you headlights wires and probably want to run them down your frame up to radiator support, you will have to tub the firewall to tuck you 20, have to cut the inside of ur fenders out, relocate alote of wires and relocate your battery or just raise it up in the back youl have to cut out alot in the fender wells. as for your a/c goes i ditched mine i said the hell with it it is a show truck who needs a/c besides im shaving all the vents ne ways. but you would have to build a new blower box if you keep it. and if your bagged on 18's now and have 2500 bags in the front youll probably want to ditch them and put some 2600 bags on there that way you get the lift you need with the 20's and if you do that you'll need to really notch the spring pocket alot. well thats all i can thinkof right now. good luck
