I found the item on moparpartswarehouse.com
Item: Convertible/soft top, Frame and components, Lower frame, Lower frame Right - 4 door - 4 door
I ordered it and entered the VIN for my Jeep. I then received an email stating that the part I ordered was out of stock. I called to confirm and they re-ordered the correct part based on my VIN and it turned out to be half the price! I paid under $40 for it.
Honest mistake by my friend. I'm sure he'll pay, but I won't kick his a$$ if he doesn't
