First, since most of you guys probably have aftermarket seats installed for road racing I am posting on here. I get all this (1)Base Adapter (2) Side Mount (3) Seat Track Set (4) Base. And the pictures below are what I receive. From what I can see there is no way in hell this stuff bolts up. Maybe the people who installed this before can help me out. I am fully aware that drilling may be involved....but how the hell do you install this ****! OH by the way this is going in an 1988 Honda Civic STD Hatch

 

From looking at the 2nd photo down, it looks like you've got one of the tabbed Sparco seat base kits. This might help...
