How can I tell the difference between a regular sp4 and one that is fully loaded?

At first glance the regular SP4 doesn't come with a spider spacer. That should be the easiest to tell.

Wow

as far as cooling though does the bottom of the basket have a hole in it if the cooling option was picked? never seen an sp4 by itself so have know idea how to tell them apart

Post a few pictures. We could tell you.

when I meet up with the person who has them I will indeed do that but for now I was just hoping you could tell me by what it looks like

Is somebody trying to sell to you used?

^yes

you can't see the cooling..it's inside of the motor, top plate is different on the sp4 and what not.

 

spider spacer would be an indication and is obvious

thanks nick
