Cartridge mounting

I had a grado on a 303 and the screws were right side up. I’d ask the dealer why as it’s really not that difficult to install right side up. 

Thanks for your input, I just picked it up this afternoon and with so much going on, didn't really notice it until now.  I'll bring it back to the dealer tomorrow.  Thanks again.

The dealer told me that this is the better way of mounting the cartridge with the screws upside down 

Better or easier is the question here I think.  How could there possible be any difference sonically whether the screws go one way or another???  Better, because it's easier and probably faster to do it that way and less chance of messing it up, I'd bet......but we never got into that, instead our conversation turned into a yelling match because this was not the original cartridge that I asked him to put on for me.
