I assume your talking about a base plate so you can tow it behind a motorhome? It's not a bad job. Took me and my son about 4 hours to install one on my 2011, and thats with running up to the hardware store for a drill bit. Good luck

 

That 32mm tool is perfect for oil filter cap removal standard socket is to tall and hits the intake runner , money well spent!!!

 

Cheap 32mm socket from Harbor Freight Tools, cut down with my chop saw. I paid about $3.00 for it almost 7 years ago and have used it for every HHR oil change on our 06 and our niece's 08. There's just enough taper at the top to clear the manifold.
