I dropped my car off today at a local shop here in Charlotte,NC to get the 4:10's installed.They gave my a great price and after asking around i found this shop to be a good one.After reading all the posts about the 4:10's the past few weeks i just had to stop thinking about them and just do it.I hope i am not dissapointed in them.I don't know what the next mod will be because the gears are the only thing i have besides the flow master exhaust.Thanks.
