Questions about a five lug deal I found

[68c10rat]

Ok, I have found a full five lug swap,front and rear. The guy is looking for $400 all of it,he said he would drop the k member and give me the whole deal,and he would drop the full rear axle and give me all of that. Now I am planning on bagging this truck so that is basically the question,does it matter what year this is under b/c it looks like mine,it just has a set of z71 wheels on it,which I would get rid of in favor of a set of rally wheels with the smooth centers. He also has a decent cab that I am going to purchase as well. What do you guys think though,is this good or right on as far as price?
thanks
