what are these called and where can I find them

outers are sill plates for the early Gen cars the inners are carpet hold down trim or inner scuff plate molding. I could care less what others call them since they aren't correct for the early applications later applications

incorporated the inner hold down and the outer sill plate into one piece. or you could almost call them inner carpet plates but not sill (as in outside threshold plates.) the ones you Call sill plates in that picture ARE sill plates but the ones in his post are Inner scuff plates or carpet hold down moldings in the trimmer business
