Rick,
I just finished the wheel well modification and followed Jack and Vivian's excellent description in Irwin's website. I used about 4 cans of `Great Stuff' foam sealant which will harden as required. (about $3.50 per) You might want to have a couple more on hand just in case. Be sure to apply a `thin' layer of foam each time to allow it access to the air to fully cure. I layed one layer on too think one time and the middle of the foam was still uncured two days later. You need to allow the foam about 8 hours to fully expand and cure before you add the next layer. For this reason assume this job will take about four days.
I used two one piece sheet metal pieces and found that a 36 inch long piece, 10.5 inches wide will fit the well of my 2619 nicely and follow the curve of the tire. I'm not sure the well is the same size for your trailer. As described, add tabs to the sheet metal to affix it to the existing structure. To hold the sheet metal in place I used pop rivets and/or wood screws depending on what was behind the tab.
It's really not a terrible job if you are all all handy with tools. Feel free to email me directly if you need more help.
