Installation Steps 

Remove OEM seat. You will then need to remove OEM rails from seat. 

Bolt the OEM seat rails back onto the car. (Handle will always be closest to trans tunnel. Leave everything loose to assist you in fitting everything together easier.

Look at settings above and find the dimension your seat falls under. There are 3 possible configurations so make sure you look up your seats published width before starting.

Configure Garagistic brackets in the configuration of the settings above. Leave everything loose. (Tall side of bracket should be towards the front of the car) like diagram.

Grab seat and install on mounts. Use the hardware as shown in your diagram above. Leave everything snug. Move the seat up and down until you find what is comfortable. Usually the front the of seat sits a little higher then the rear to angle you back slightly. 

Once you like the seat position tighten everything. Check that seat slides back and forth smooth. If your seat doesn't move check that hardware is not touching the slider lever, everything is properly greased that nothing is misaligned.

 

Optional Seat Belt Mod

If you find yourself having a difficult time bending the stock seat belt receptacle to fit in the opening on your bucket seat, we've found a neat solution using OEM parts. 

For this mod, you will need a spare dual seat belt receptacle from the rear seat. If you are modifying your track car, it is common to delete the rear seat which leaves you with a spare dual seat belt receptacle. If you want to do this mod to both front seats, you will need to source another dual receptacle for the passenger side front seat.

The photo below shows a stock dual seat belt receptacle (left) and our modified version (right).

As you can probably tell, this is a very straight forward modification that just requires some cutting.

Cut along the dashed line as shown in the photo below - 

That's it! 

Now enjoy your more flexible front seatbelt receptacle
