How do I reinstall my timing damper without a threaded crank?

How am I going to reinstall my damper on my 170? It didn't feel like the crank snout was threaded inside. It's a 66 170 motor. The engine ran smooth with this damper on there but it defnitely isn't new. I had it carefully bead blasted and repainted. The machine shop guy said they use to just beat them on there with the motors that didn't have threaded cranks. I don't know if this one is good enough to beat on. I don't where to get that tool they show in the 65 Plymouth service catalog. It looks like a pulley turned around backwards with a forcing screw pushing it on.
