You can always go to an M2 frontend,it worked for me.As for the rear,the cheapest way is to take some leaves out of the springs.Several other ways to go,this is what worked for me on my 55.Course this winter I will be installing new rear suspenson,new 5 leaf rear springs,new hangers ,perches,and shocks.Will also flip the rearend.A lot of these guys will tell you ,aw just leave it stock height.Its your truck,do it your way.They are all nice,stock or steetrodded.
