blogger template help needed

ok i was wondering if anyone knew how i could add some adsense on the leftside of my blog. it is host on blogger. i want to add either 160x600 or 120x600 on the left. as you can see under the iwatchebay banner there is a blank white line under it that is here i tried to add some adsense but i want it to be 435 width not 468. does anyone know how i could get over that or if i cant?
