Overflow bottle

I haven't seen the aftermarket bottles at advance or autozone...etc but the ones I have seen were very thin material,very soft.I do agree that beauty is in the eye of the beholder,have seen a lot of aftermarket parts,custom included that looks good when installed.On the other hand I have learned to be very careful on some products especially when it comes to plastic,some just don't hold up very well,but I will check at advance to take a look at them,Thanks
