Not too sure how the RCD 6" Is ridiculous as one of you said, i have one and theres plenty of members on here with it without issues....If you do a search theres 3 or 4 i remember on the forum who did the 6"+3"body. When you do that you need to weld an extension onto the steering shaft which most companies wont do because of liability.
