SD/GPS shield pins in use?

Hi, I have a Uno shield with an SD card and a GPS. I want to run this with a Nano but need to find the pins that are in use by the shield. It looks the same as this. http://store.linksprite.com/gps-shield-with-sd-slot-for-arduino-v2-b/

This looks to be the schematic for it, but not sure how to find all the pins in use. https://s3.amazonaws.com/linksprite/Shields/GPS+shield/arduino_gps_sd_V2-B.pdf

The board is painted on both side so it is hard to follow tracks but the underneath side looks to have a trace to D10 and the top side to D11,12,13. But, I can't find those mentioned on the schematic so they may not be connected.

I can't find anyone involved with the actual board to contact regarding the pins.

Thoughts? Help?

I don't suppose there is a nano-shield adapter that can use Uno shields?

Thanks

This one looks like it has pads for female headers to take a UNO shield.

Thanks, after posting, I found something very similar but was looking at a prototype shield I have and it may just work by putting the Nano on, then the Uno on top.

I'll report back f I have success. No report, no success. :)
