if he wants to daily drive it then i doubt he is willing to relocate the gas tank. the thing about "reverse bars working aganst the forces of gravity" is BS. if it was true most of the 4x4 trucks wouldnt use it for the front diff (F-250 , F-350, Dodge Ram, Jeep, etc.) they have reverse mainly for crearance but they wouldnt have it if it wasnt safe. so dont lisen to the guys that say reverse 4 links are dangerous, unsafe, and dont handle good are usualy full of $hit. the only down side is when you go over a speed bump the truck jerks forword slightly when your back wheels starting to role down the bump. its not very noticable if you go over it slow over it ( whith your probaly going to do any way) and have longe enough bars. if you want a bolt on kit go to Cando. they have a bolt on reverse cantalever kit that rides and handles good. the price isnt that much compared to the price a shop would charge you. he dosnt need to notch for diveshaft clearance because he has an ext cab that has a 2 pice shaft that wont swing up into the cab when airing down.
