mine came from www.verticaldoors.com. I don’t know how many manufacturers there are for them, but it seems that a lot of companies on eBay and such sell the same ones.

I paid about 1100 for mine, but they seem to vary a lot in price, from seller to seller. According to my friend, the instructions are entirely useless, and there was missing hardware (which was resolved quickly, luckily), and they don’t tell you where specifically to cut into the fender etc. it sounds like it’s a fairly complicated install that requires a lot of outside research, due to the uselessness of the instructions, when it boasts a “simple bolt on job”. In addition, it’s definitely a two person job to install the doors. It took them a while to do it, and they’re both very mechanically inclined. It also requires moving the windshield fluid tank, as it is in the way of something. I just took mine out since I only drive it with the top down, and I may get an aftermarket one but I don’t know.

the handle is just the interior door handle that comes in the vehicle. It’s awkward and I recommend an aftermarket handle for sure.
