They invited you to view the REG REAR SPG 8'-18' WHT ***USE 26-2082 *** Product.

Cost of the part alone is $115 plus any taxes and shipping. Be sure to verify this is the correct part with your dealer.
Since it is involving the spring I would suggest you have the dealer or service center do the work unless you are very familiar with working on spring loaded parts. It is more than a one person job.
I found this part on the PPL website, Carefree, Fiesta, after 1997 parts listing.
Hope it helps.
