Question:

Im putting this on a 2011 Highlander and would like to run a tap through the holes on the frame, but I cant seem to find out what size tap I would need. Can anyone help me?

The Curt # 13534 uses M10x1.25 bolts so you will need a tap that matches. You could also use a thread chaser to clean out the existing threads rather than cut new ones.
