As the title says, I've got a 1968 4-door Skylark with the non-split/non-armrest front bench and I'm needing seat covers for both front a rear seats. It looks like Summit carries some different covers, but it's hard to tell if this is what is needed. Has anyone managed to find seat covers for these somewhat rare seats? Here is one that I've found....Will this fit? https://www.summitracing.com/parts/pui-68us12c/make/buick/model/skylark/year/1968
