I got some future retractable seat belts from Alvin in Dalton about 5 ears or years  ago. Since Stupie aint into that modern safety baloney.. The back seat would jam up the rewinder and it was a  frustrating to buckle up.   Eurecka!  We had these old cabinet doors my piro spawn wanted to burn laying  around.... so I have new and Improved   "Buck Board" seating in the back.  Sweet huh?  SC
