This is a great kit for my Wild Willy 2 up-grading! Great product over all. No problems during install. You can use the original front knuckles on a WR02 chassis. It would be prefect if the manufacturer can give the recommendation of Tie-rod length setting for different WR-series for the player. It was highly recommend to all WR players! It lets a cool look for the model and work well for the kit!
