I bought the kit off amazon..heres the one i ordered:
Robot Check
As far as the pipe, i bought that while visiting the inlaws in St Louis and went to Menards. mine didnt have the bell on the end though, just to let you know. although, i had to cut almost 2 ft off anyway.
Next step is to figure out how i want to ultimately do my Motocross setups...right now ive just been using a 2x4 with the strap hooks going thru the 2x4 and attaching to the loops in the floor already
