If you have an Orvis dealer nearby, take your reel there and see if the current model reel foot is any different than yours (I suspect it isn't, but there's only one way to be sure) If it is, maybe the store will be able to order a new reel foot, or more likely they will send the reel back to VT and have it changed for a nominal fee.

The other option is to remove the reel foot and CAREFULLY grind it down to fit the reel seat of your choice. I did this ages ago with a Medalist that I wanted to fit onto a sliding-band reel seat, and it worked out fine.
