Guys, I just found rack and pinion that fits c beam perfectly. Company out of Japan makes them. web site: KHK Gears - Gear Manufacturer see attached pdf (cut sheet) I filled in request for pricing, if it is affordable, maybe "Openbuilds" can contact them and add the parts to their list.
Thank you Harry, I have bin looking for affordable rack & pinion for a while now and that is the first time I came across web site that you point to.
Harry, I tried to order them from the web site but it seems that they do not ship to US. and US store does not have this item.
