I converted a mid-to-late 70's Fuji Finest to 700C a number of years ago. Some things to take into consideration: Are you going to keep the same hubs? If so, you'll need to change the rims and the spokes. Or are you going to install new hubs, as well? If so, you'll have to fish around a while to find one with 120mm spacing (I assume that a bike of that vintage has a five-speed freewheel or, at the most, a 6/7 speed, which used a 126mm hub). Those will be kinda hard to come by new, but you should be able to find some used. Since you've installed a cartridge BB you might want to think about a PW hub set, too. It'll give you a stronger rear axle. Next, you'll more than likely be changing the old brakes for a pair with longer reach. Dunno what the GS has now (CP or SP), but you may not be able to move the pads far enough to engage the smaller 700C rim. There are plenty of newer long-reach double pivot SP brakes around the market if you go in that direction. How badly worn is the FW? Is the chain skipping? If so, you may need to upgrade that, too. Good luck with that - those are getting harder and harder to come by.
Most of all, be well.
