I have been looking around for part #500001 (front lower control arm) red cat has it for $45... I have seen it listed for $27 - $69 I was just woundering why the large price differance? and if the Alum. are worth the $$, It took a hel-of-a hit to break the plastic one.. Full speed in to a wood fence. off centered so that the tire hit 1st.
