Without pics, or even a model number, I can't tell you for sure, but I'm going to venture a 'Yes' anyway. Given the inflated price on many old Bridgestones, I'm willing to bet you have a lower end model, and the budget 'sport touring' bikes almost always had greater clearance than their more competitive counterparts. Given the general Bridgestone philosphy, even on the days before Peterson had really taken over, long reach calipers seem likely.

It's elementary my dear Golfer.

Unless of course you have cantilevers, or a racier bike, or I just made a stupid mistake.

And it's always possible to simply re-use your current brakes if you have the 4mm of vertical adjustment. Or else if you have enough metal to file out 4mm of adjustment space.
