Car sponsors has been a great asset for not only discounts but being able to find parts and ideas for builds. For example the vertical doors I purchased from Mr Body Kit. I seen the sponsor photo of a mustang with the doors and I wanted it.
Instalation was completed by me in my garage at my house. I would say the installation difficulty would be a 4 out of 5, but anyone with basic tools and mechanically inclined can install this kit as it is made for this vehicle.
