L2550 1987-ish. Steering relay shaft from steering wheel shaft to front steering box consists of shaft with u-joints welded on each end. It's toast...tractor is nothing more than a navigational hazard without it. Kubota claims NLA on this part 32420-16670 or 32420-16672. I need a source for salvage item in usable condition or source for u-joints and I can cut/weld. U-joints are same both ends, splined with split M8 clamp. Any ideas greatly appreciated.
