2. Mark on the floor the location of the 4" round tube, the 2"x 2" tubes, and where the frame steel mount
plate is located (between the X tubes under the seat).
a. Use a marker and a ruler and measure 2" towards the outside of the car from the inner seat belt
mount.
b. Mark a line from this point forward 2 feet. This is where the 4" round tube is.
c. There should be rivets along the 2"x 2" tube and ¾" tubing, so finding these is easy.
3. Look on the underside of the frame to find the steel plate between the "X". Mark this on the
aluminum.
4. Test fit the seats on the floor to find where it is most comfortable. (If the seat to steering wheel
relationship feels good but the pedals do not you can change the height of the brake pedal by adding
or removing the master cylinder spacers and both pedals will bend side to side if they are to close to
each other or the gas pedal).
5. Outline the seat on the aluminum.
6. Flip the base of the seat forward, it is held in place with Velcro, and compare the lines drawn on the
aluminum to the seat frame.
