Torque Wrench
I'm normally an advocate of buying tools, but this is literally something that gets used once or twice buy the average backyard mechanic.
As it happened I had to give back the dial torque wrench I was using and finish my install with my Snap-On inlb click type wrench. I just treated it like a go, no-go gauge and snuck up on the rolling torque a couple inlbs at a time until the wrench didn't click over. I think you will not see a significant variation in readings between the two types of wrenches.
