You probably have a 120mm OLD (over locknut dimension) rear hub. A 7-speed freewheel will probably need a 126mm OLD hub to fit. So you will need an axle about 6mm longer. Actually, if it is a quick-release axle, you can probably get by with the current one. There won't be much axle sticking out past the locknuts, but you don't really need much more than couple mm with QR. I've spaced 126mm QR hubs out to 130mm using the same axle and had only a few mm sticking out on either side and it works fine. You will, however, still need a longer quick-release skewer.
