I bought from them as well, and yes, they sold me extra leather so I could do my door inserts. I als bought seat heater inserts, and they're nice products. If you buy the seat heaters, make sure that you cut around ALL of the hogrings or they will ground out and start cooking your foam. Ask me how I know....
Great product, I highly recommend them. All in all I had spent around $1000 to completely redo my interior (dye, solund proofing, carpet, leather, ect) and it looks and smells brand new. Now all I need to find is a MOMO steering wheel at a decent price....
