Is Replaceing A Tail Light Lens A Do It Your Self Job ?

Just purchased a 2001 protege lx and the rear right tail light lens is cracked .
I've sourced the whole assembley and it's 65 bucks .
Just wanted to gauge how difficult a job it is , i'm pretty savy so it should be ok

also , where can i buy the plastic tacks or plugs that hold the truck interior flush on the car and back of taillights

hope i enjoy the mazda experience , so far car is a beast , but consider i'm used to driving a toyota truck and a 914 porsche .

this mazda is way more powerfull

please any advice help s (IMG:style_emoticons/default/00000732.gif) (IMG:style_emoticons/default/banana.gif)

It is really easy to replace all you have to do is take out some pins holding the carpet in the trunk on and then unscrew the 3 bolts and pull it out then just take the lights out and put the new one on.
