You can get the boot from Redlinegoods.com. they are one of our site sponsors and i personally have both the shifter boot and the ebrake sleeve and i love the looks of them. The door inserts you can get them from topshop or keep your eyes open on the for sale forum.... As far as seats go, depends on what your looking for. I know there was a guy here from the 350z forum that was selling some red BRIDE seats. just do a search for Holding Monsters. good luck buddy.
