JB 4.1.1 on OG Droid, Where do I get Gapps.zp?

Also I need to find out why I can't mount the SD to my computer? I need to mount it so I can add the apps to the SD? Any Ideas!
 
I'm not entirely sure but I think you have to use ICS Gapps.zip for JB on OG Droid. There was some requirement that the Droid doesn't meet, I think its a RAM Issue.
