1500 isnt too far off. There are different ways you can do that front too. I saw specific kits for the front of 73-87's when I did mine, but I went with a later model 91+ cup system on mine. (it installs differently) There was more fabbing on my part, but the parts cost less than going with a kit that someone else had to do more fab work on, making it cost more.
I wont comment on the rear....there is already a thread going on here about that.
