Rear Corner Lower, Left 68-71. 211-813-355R

These are made for an early baywindow, but will fit a split bus with slight modification. 

The curvature of the bowl is an excellent match, but the panel does not come with any return edges, but there is spare metal at each end to form your own return, not ideal, but still a decent panel. 

LEFT SIDE Fits early bay (all small rear light) also fits split bus
