These are installed just like factory covers. These are vehicle, trim level and feature specific. Katzkin kits are intended to be professionally installed, or by those "DIYers" with firsthand knowledge of auto upholstery.
This company is amazing. They reach out immediately to find out specs of the vehicle and then let you know exactly what may be going on especially with the pandemic ! On top of that they made sure I received my package sooner even though they didn’t think they’d be able to with everything going on ! AMAZING JUST WONDERFUL COMPANY
