i work at a body, aftermarket parts rarely fit the way you want them to without modifying them. but, as far as him saying he didn't want to bondo the gaps to make them fit better...thats not his decision. it's what the customer wants as long as he pays labor/materials. body men at my work love it when the customer says "just make it work" because that means easy money. they may not want to modify the kit to make it work because they don't want to mess it up and have to pay for a new one. in my opinion, you should go there raise hell, threaten a law suit and then have them redo the body work.
edit: i just now saw the pictures, i didn't read that far into the thread. WHY IN THE HELL DID THEY PAINT THE CAR WITH THE BODY KIT ON THERE!!!!!????
