I installed a trailer hitch today . it is for a 1973 2006 chevy pickup . Teardropy turned me on to it . All I needed was two lengths of 2x2 tubing 10 inches long , for a spacer between frame and hitch . This will locate the hitch just below the stock bumper . $115 with shipping on e-bay . It is well made and will pull 6.000 lbs with 600 tongue weight . Looks like it will fit any of our trucks .
Looking at the pics, on the safety side, depending on what you might be towing and the tongue wt. I wonder if the 2x2 tubing should be longer-towards the spring. This would spread the weight over a larger area.
Thanks to Chris for posting these pictures that I emailed to him.
As you can see I fabricated my own SS bumper irons which tuck the bumper in and up. I wanted the receiver just under and basically flush with the bumper. I fabricated the spacer that is between the bottom of the frame and the mounting flange of the hitch. The hitch is one of the adjustable width type made for motor homes. It was the closest that I could find for the right drop and to allow a flush mount and allow exhaust to exit over the hitch and then turn down under the bumper.
