I'm working on a big upgrade kit with a ton of hardware. Also a overhaul to the rear suspension parts. They were made out of the flexible plastic and really the only weak point I found on the whole truck. I will be making a video when its ready to go of all the differences and how to install it. Anyone interested? No price figured out yet.
I also decided not to sell the canvas covers.
