Try doing a Google search for "Honda CR-V Front Bumper Diagram". Several diagrams should come up indicating the mounting details, etc. for the front bumpers of several model years. This may help you to see somewhere you can mount the bolts. My only suggestion, not being at all familiar with the CRV, would be to utilize the connection plates on the tow bar base plate. Hope this helps some - good luck!
