Macgregor PT3 shaft tip diameter?

I came across some almost-mint looking Macgregor PT3s at a local golf shop. Before I pull the trigger, I wanted to know if the shaft diameter on the weaker-flexed Macgregors was something smaller than 0.355? To the naked eye they look thinner than a normal shaft. I don’t want to buy them if I would have to rebore the shafts as I don’t have the equipment for that presently.
