Alright! Thanks to member Benjoke for the lid swap, it took a bit longer than expected specifically because we needed to pull out wiring (which i didnt expect to do, because I thought everything was the same) but the BRZ has a button for the trunk release too so that added a little bit of time. Anyhow, this morning it took the two of us, and a friend about 2.5hrs to do, but it was hot as hell and we were taking our time, this whole swap should take like 45mins tops, we couldnt believe that places were charging $400 to do this..eeek
anyway:
BRZ lid on FRS (mindboggling, scion BRZ!)
After swap, we ended up unbolting and keeping our own respective pieces that are above the license plate to retain the trunk release button on Benjoke's BRZ.
