NAV WHEELS AND FRONT WHEELHOUSE.

I SEE ALOT OF PEOPLE RUNNING 18" NAV RIMS, ARE THOSE RIMS THE SAME LUG PATTERN AS A 90MAZDA B2200. ALSO WHAT IS THE LUG PATTERN ON THE 90 MAZDA B2200. ONE MORE THING TAKING OUT THE FRONT WHEEL HOUSING IS THERE AND CUTTING INVOLVE OR IS IT JUST SCREWED IN THERE. ANY HELP WOULD BE NICE.

No they are not the same lug pattern as a Mazda. They are 6x135mm and a Mazda is 6x139.7mm. To put the on a Mazda you will need to get them redrilled.

To take out the wheel housing(inner fenders) you need to cut them out.
