Ive dont tons of heli-coil installs. Couple tips; Chamfer the hole a little after you drill it makes starting the tap and insert easier. Make sure you drill and tap deep enough for the entire thread insert to go slightly below flush and also allow you to break off the tab, they have different lenght inserts if needed. Use a punch slightly smaller in diameter than the thread to break it off the tab, too small and it will bend or deflect your blow. Its a huge pain if you find you need to drill deeper once you've tapped the hole. They are super strong though and I put them in anything that requires the bolt removed all the time, even in steel and iron parts, they are just much more durable than the base metals and they spread the load over greater area. I would also just put one in the other hole since its most likely damaged and your doing the other one anyway.
