Work and Play adding skid wheels

we put the clamp on ones on a boat trailer we had. Boat was a V Drive so prop guard hung down real low, always drug on driveways and eventually ground right through the steel. I replaced the prop guard and added the wheels, worked O.K. but that reduces the clearance even more so be aware of that too. With the weld on ones you can position them more easily to get them just below the existing skids.
