Well we all know that a dog of that size should be able to deal with that little turd dog. The question is, are you gonna be able to handle the chaotic noise that you will always hear from them?
I dont think there would be much of a problem at all. Just unbolt the old, bolt in the new, unless I am seriously mistaken. The only minor problem you may have is the holes being a tiny bit off.
Just knock it off with a wire wheel and repaint it. Not hard at all. I am going thru the same thing. If you dont have a grinder, they make wire wheels for a drill. If no drill (heaven forbid) bust out the ole sandpaper.
This doesnt have to be true if you dont want it to. Just get a 15" wheel with some small tires on the back. Less weight, quicker car. The only thing I might be worried about is blowing off the tires on the launch.
