well you could return it, again, but ur rs will start to hate you. well if your g35 works well (before the dogbone broke) then i would suggest buying some more durable parts. if it seemed to have another problem as well then just go and return it and hope for the best.
well you could order new ones from them but since it seems they may break again you should get stronger ones. there is alot of parts made from aluminum for gpm and other companies.
for some stock parts this is really the only place you'll find them excepts ebay sellers.

for some aluminum there is plenty of sites try here at atomic mods, you can get just about anything but the prices are alot. i suggest just looking through ebay.
