I agree with BJ.
I would drive on a deserted road at about 35mph and begain the install. You'll even have more foot traction now that you have the liner. Leave the seats out so getting to every bolt hole easier. And for gods sake man, look up every now and then to be safe!! <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" /> <img src="/forums/images/graemlins/shiner.gif" alt="" />
