Saw an 80 on ebay a few weeks ago with the "optional dash cup holder" Pictures showed a pop out diving board style drinkholder right above the stereo. The plastic piece that covers that slot is the "cup holder cover" in the toyota parts catalog but oddly there is no cup holder available. Local dealer took interest in puzzle and came up empty - they suspected a cup holder for a toyota truck or 4runner must fit there. Anyone solve this puzzle?
