Has anyone attempted to redo the black rubber covers surrounding their seat stands? Mine are old and torn, needing to be replaced. I've searched a few sites to find replacement material and all I've found are the top covers for buses up to '79 (but does not work for swivel seats) and side covers up to '76 (which won't fit, as the '77, '78, '79 seat stands are taller).

I have a '78 westy with a front passenger swivel seat. Any suggestions are appreciated!!
