Leveling kit?

i got a 2 inch leveling kit (coil spacers) for my 99 ram... from rough country.. it didnt come with any blocks for the back. so now the front of my truck is a little higher.. kinda looks dumb and iwas wondering what size blocks for the back i should get? 1 in or 2 in??... or just go with add a leaf(s)








thx for the help
