I purchased a new 500 series steering box and also ordered the steering kit, which included the pivot arm, idler arm and center link. I have had orders in for this part for 4 months from CPP & Eklers. My order was canceld by CPP and Eklers informed me that these parts have been dicontinued. I'm sure this is caused by the devastation in China. Do the original manual steering parts work with the 500 series steering box? Do the parts need to be modified? And if these parts do not work, doe's anybody have a suggestion on where to get these parts. Thanks, PATS55
