I was off work today and the weather outside hit a balmy 51 degrees. So I decided to work on the seat bottom grid on my 245. I recently bought two new seat grids from IPD. I only had enough daylight to work on the front passenger seat. The seat came out quickly. Took me a while to remove the old grid and springs. I put a layer of duct tape on the foam to help prevent some of the wear against the springs. Took me a while to get the hang of stretching the springs back into place. The new seat grid seems better made with thicker wire to support the seat foam. After getting the seat back in place it is more comfortable. I also noticed that I sit up a bit higher now instead of sagging down. Overall 4 springs had come undone. The weather is supposed to get cold this week so I'll wait for a decent day and do the driver's seat.
