Need help finding plastic part for roof racks

[Wildmoose31]

Im new here and if this post is in the wrong place I apologize.
Yesterday I went to Mohegan Sun (huge casino, eastern ct) and after a wrong turn or two I ended up driving into a parking garage for employees only and not the "high clearance" garage i wanted to go into and then I finally found my way out and to a parking lot that was open, but In the employee parking garage I managed to hit my kayak racks on a low overhang or two which didnt hurt the kayak racks from yakima but broke the plastic pieces which held the crossbars to the rest of the rack. Now i am wondering if there is any way that I dont have to spend the 150+ to get new crossbars and just get new plastic pieces for the end. (xterra 2001 SE)
any help will be gladly appreciated.
thanks alot
