Vert Top latches

I got a new top put on my '89 a few months ago and when they installed it they said i needed new latches. I finally got the time and money to pick some up off of ebay and got them a few days ago. So I was wondering if they were something I could do on my own or if I should take it back to the shop that put the top on and have them do it. It looks simple enough, but after the money I put into the new top, I really don't want to screw it up :shrug:
