I kept with the theme of 1960's hotrod and kept the interior basically stock with new materials. The original seats were in good condition so they were reworked with new foam padding and covers. The covers were laid out with a newer look incorporating the Chevy "V" into them. The armrests were made from hard foam and fiberglassed and were designed to mimic the old armrests as well as the dash "humps". The large size was needed to house the speakers and window and lock switches. The headliner is stock other then the material and the inclusion of the tweeter speakers. The retractable 3-point seat belts came out well and look "factory" the way they exit out of the beltline.
