helicoil will be fine if you do it right.. you can buy the kit comes with few coils the tool to turn it in and a tap and bit.. i think alot of ppl just stick a helicoil in there and hope it works but you actually drill hole out with bit supplied and then tap it with tap supplied then turn in helicoil and break of tab .. stronger then new cus now your turning on metal and the alum part never moves or get worn..
