Attached you will find seven (7) labeled pictures and dimensions of my 987 trailer hitch. I think the pictures show most of the dimensions that you will need. This was fabricated last spring and used last DE season to pull my HF tire trailer. The long back plate is 1/4" steel, the L-shape tongue 5/16" and the license plate holders 1/8". The construction requires significant welding. For safety, the tongue is both welded and bolted through to the bumper. The main hitch bolt was fabricated from scratch using the tow hook in the tool set as a model. The spacers (1/8" thick pipe) have steel washers welded to the tops so that they can be inserted into the 3 holes and will not fall through before the hitch is put in place. The hitch will NOT work without them and will damage your bumper cover. The only modification to the car are the two extra holes in the bumper cover then drilled through to the actual bumper and tapped to fit thread. These two bolts (do not over tighten--these are steel bolts in an aluminum bumper) only stabilize the mount and prevent it from turning on the main bolt which carries all the load. I put Loctite blue on all three bolts during assembly to the car. Have used on 5 trips up to 300 miles and at speeds up to 85 mph without the hitch ever being loose at the end. I do check it and the trailer periodically during the trip. This hitch is way more work to install and use than the Will Hitch, but having used both, this is clearly more stable. This was for the most part built at a local independent Porsche shop. It took 4 hours to make, not including the welding of the main bar. We had to figure this out as we went along. With a design and measurements already created, it should take less time and money $$$. Of course this design is only a suggestion that has worked for me. I do not guarantee the device or warranty it's performance or dependability in any way. Mark-NY
