Now
here is the way a company should sell a kit. I don't know anything about the company or the kit. What I do know is they mention 1/2T and 3/4T and they mention the correct frame widths, they have you click on 1/2T or 3/4T and add which kind of shocks. TCI does a very bad job and sends wrong parts as I have documented on the Speedway link.
What's funny is that this company sells a lot of TCI kits!
