First off my Camaro is a 2011 V6 2LT Convertible. It came with heated leather and has the usual side impact air bag, power recline, and manual fore and aft adjustment.
I used all factory items purchased thru the dealership at which I work.
I will give part number then description. Items I purchased are...
#13581767 Seat frame
#22821284 SIR Bracket
#13272975 Bolt (you will only need this if yours break or strip like mine did... 4 total)
First I had to put a SPAC case in order to get the frame as it went directly on Back Order.
As you can see it comes with all the motors.
