68 Impala seat covers

[Impfan]

I'd like to purchase a seat cover with the cloth inserts for my 68 Impala Custom.However,most places only carry the full vinyl cover for the back seat as a single item.In order to get the cover with the cloth inserts,one has to purchase both front and back.Does anyone know a distributor that carries the cloth option for the back seat only? Thanks,Impfan:confused:
