Try to match ractory rally red or not?

73 duster rallye red, plan on respraying exterior after epoxy primer but not jambs trunk etc.. for now atleast. Car is summer weekend driver. Was going with tcp restoration shop as thats the epoxy primer I have. Is there an "off the shelf" color that matches the factory color? The custom mix is about 200 more than picking a off the shelf, and to be honest I wouldn't mind a brighter red.
