On the fender skirts, see here. You will have to measure your to find which one is the right one. And they have white or a gold color. The gold may not be a super match to your older ones. The older gold ones I have seen on a 2006 or 2007 were sun faded so badly, it is hard to know what the original looks like.
You can buy direct from Icon, or search their part numbers on the web. Sometimes Camping World or even Amazon has the Icon brand cheaper then selling direct. Icon makes good products quality wise. I have bought many of their products and had very good results with them.
The Sunline spare tire cover, years ago there was some for sale by the manufacture to unload them, but I have not seen an actual Sunline aftermarket one made yet. Maybe another club member has and can post. Many have bought generic tire covers. One word of recommendation, buy light colors that reflect the sun. Black is common now and other dark colors for tire covers. While they may look good, dark color covers create excess heat that adds to breaking down the rubber in the tire faster due to the excess heat created.
PS. If you want to see what a white ICON fender looks like next to the gold siding, let me know. I have one in the barn now I can take a pic of to show you.
