I'd like to install a receiver hitch onto a 4dr 2003 Accord EX-V6 that would carry a bike rack for two adult bikes. I found a hitch that seems to do the trick - http://www.etrailer.com/productdetail.asp?partno=60953&vehicleid=5492&yearfrom=2003&h=e Only thing is, they have a little add-on disclaimer that says "Heat shields require drilling on V6 models". I am not sure what these heat shields are and where/how they attach, other than the obvious, but I am also a bit reluctant to drill the frame or anything else the hitch may attach to on the car body. But if I have to drill, I wanted to see if anyone had any luck installing this, or any other hitch for the same purpose on a 2003-2004 V6 models? Thanks in advance. Sergey
