How much trouble will it be to rebuild the front end?!

UPDATE!!

please look at my other post (http://www.forabodiesonly.com/mopar/showthread.php?t=79013)

I believe I have a 73 or later K-member. I already ordered my kit from P S T, is everything that comes in my '67 kit the same for a '73 dart (besides the idler arm)? Or am I going to need to return my entire kit?
