Front T/A Chin Spoiler's

I've decided to go with some new T/A, style Chin spoiler's for my 73' Rallye. They are new from Year One. When I asked if they came with mounting bracket's, the guy said, I would have to use my original one's. I told him that the car did not originally come with front spoiler's. Question: Is this small project as easy as just drilling a few hole's, and getting some nut's and bolt's at the hardware store?
Or is this going to be another can of worm's project for Pat?
Thank's Guy's!
