Here are two pictures of the rubber boot for the 4wd and H/L shifters. The hole in the cover is roughly the same as in later models that came with the rubber boots standard.

In the following photo you can see that I didn't cut the underneath lip to clear the captive nuts, since all were removed. I put some duct tape to cover the holes and prevent fumes from coming in.

It is possible that you might need to fix somehow the rubber boot to the cover. The boots on mine (except the transmission shifter one) are original from Nissan. The aftermarket ones are not as flexible. I once tried them some 20 years ago, and it was specially a problem with the parking brake boot, that lifted from one side of the cover every time that it was engaged.
The boot for the shifter is from a Mazda or Ford Courier pickup truck. It is hold with tape to the cover since there's no other choice. Since on top I have a carpet felt and then carpet, you don't ever see the redneck solution.
