I have a matching pair L&R rear quarter plastics. Both in good condition with no cracks. They are not for a 73 model 240 as they do not have the seat belt bolt holes. Someone may be able to identify exactly what model they fit.
As is condition but a lick of vinyl paint and they will look like new.
$120 ONO plus postage for the pair. They will be worth something to someone but not much to me.
