A couple of questions:

1. I'm looking for an OEM antenna mast for my Honda Accord '93. I did a quick search on the internet and noticed a drastic price difference. In many cases it's around $50 and in others, it's about $15. Does anyone know the difference here? Is this the difference between chrome and stainless steel?

2. Does anyone know, when installing the mast, which way the teeth need to face?

Thanks.
