this is a problem where cost is a factor. I don't know how much the OEM ones cost but if they are cheap then get them. Then you at least know it wont be a pain putting them in. Why did they break any how? Is your wing really heavy?

 

they just snap in, every car has the same design, boats use them as well.

 

Yeah...the wing is pretty heavy...it is a GTR style wing that a friend got at NOPI.
