Blazer seats install in a truck question

[72supermike]

I suppose this is widely known but I did a search and looked for a while and couldn't really find the answer I wanted. So....

I have a bench seat in my 72 truck. How easily do 69-72 blazer bucket seats mount up in a truck? Do blazer bucket seats look the same as what original truck bucket seats would look like? Anything else I should know? How much would a set of blazer seats with a console cost if they needed to be recovered? Thanks guys!
