In addition to the Fiero seats I installed a new gray carpet kit over the layer of 3/8 neoprene foam I had put down. Also, new inner door panels and all the old wine colored interior parts were painted with vinyl paint.
New seat belts, steering wheel. I made new panels for the sides of the transmission tunnel.
All the new gauges are installed in the ABS panels I made for the dash.
I have gauges for EGT, Boost, Speed, RPM, Fuel level, Water temperature, Fuel pressure, Oil pressure, Oil temperature, Voltage
