Replacing A/C Radiator?!

Got my baby up and running today for the first time in too long. AC wasn't blowing cold so I had some recharging coolant and filled her up, then when I turned the truck off I heard a loud hissing sound, definitely sounded like a leak and I was able to narrow it down to this little wet spot on the small radiator up front. Pretty sure it's been on there for all 420k miles lol, you guys ever replace yours before? Doesn't seem too bad but I figured I'd post and hit you guys up for any extra thing to look out for or be aware of. First I gotta find a new one though! Thanks

 

Found one on Amazon for $78, suppose that's not too bad of a price and looks good quality
