Today we are going to install part number 11380 from Curt, and we are going to install this hitch on a 2005 Chevrolet Corvette. This is a base Corvette, with none of the performance packages from the factory installed on this vehicle. If you do have a performance package on here you will run into a problem with the muffler. Sometimes the muffler length will interfere with installing the hitch. If you have a base Corvette you can install this hitch with relatively no problems with clearances. But you may want to have to double-check if you do have a performance package. We will show you the attaching points where the hitch installs.
On the frame here, this oval hole right here, the hitch and hardware will go inside this hole here. We will have to enlarge it a little bit to get the hardware in. Then we will actually pull the hardware through the same hole. This will be identical on both sides of the vehicle. And the rearmost attachment on the vehicle will go onto the bumper structure here itself. And these holes will have to be drilled out. To enlarge the hole here, what we are going to do is actually drill out a 1/4-inch hole right next to it, and then follow up with a 1/2-inch hole. Then we are going to take our cold chisel and just run it through there to make a nice, even extension to the hole. Then you can see, you can run your hardware right in there. And you will need to repeat these steps for both sides of the vehicle.
All right, next we will install our hardware. Our plate is going to go on there, and also our bolt. Put the bolt inside, and then our plate. And there is a piece of metal right behind this hole here so you want to spin your plate where it is flat against it and pull your hardware back through.. Next we have got to drill another hole in bottom of the bumper here. And we have to do that to get access to the inside of the frame, because you cannot get to it from the ends of the bumper. Let us drill out a hole and then we will put a small hole next to it like we did in the frame next to it to get our hardware inside.
All right, our next step involved is go ahead and lower our mufflers. There is a couple of brackets that go up against the bumper here. We will take those down. That should give us enough room to slide our hitch into position. And we are going to loosen these brackets for the muffler, too, just to give us a couple of extra inches, if possible. Next we are going to lift our hitch into position. It is good idea to have an extra set of hands to help work around the exhaust. With these last two bolts here, we will snug them up to help hold the hitch up into position, and then we will drill out the last two holes into the bumper.
Next we will go ahead and drill out our holes, and we are actually using a jobber bit because the exhaust is really close to the frame, and this will give you extra clearance for the drill. All right, next we are going to go ahead and install our hardware. We are going to run our bolt leader through our drilled hole right here and then out our drilled hole in the center of the bumper. And once you have it pulled through, go ahead and install your block and your bolt. Run your block in first, and then thread in your bolt, and repeat the same thing on the other side. Once you have your bolts all snugged down, then go ahead and check the instructions for proper torque. All right, at this point we can go ahead and reinstall the exhaust. And this covers our install of part number 11380 on a 2005 Chevrolet Corvette.
