1969 Valiant questions

I just purchased a 1969 valiant that needs interior help it needs seat covers front and rear , both seats sun baked and down to the springs i priced covers from legendary but they will set me back around $600.00 has any body tried seat covers from jc whittney? they get around $280.00 for the set front and rear im not making a show car just want something that looks nice.Also there is a company on ebay(mcmahonmopars) that lists them for $365.00 for the set,looks like they have a good rating just wondering if anybody has tried these, i know i will need new foam with whatever covers i go with.And one last question is just dashes the only option for a new dash pad i will need a complete one not just the cover.
Just looking for your opinons as i am not to familiar with these cars yet.
Thanks in advance
