feather duster-mileage-cat convertor

i just checked the mileage on the 76 feather, auto car. i drive it round trip 64 mi around ozark hills and curves (small hills), 30 and 31 mpg. i drive back roads about 50 so i'm not runnin down interstate 80! when i got it i was intrigued with all the comments and notions about the feathers and lites. ( yes they were available with a t) . i have a rebuilt carb that is correct for that year but obviously not orig one. also it has a cat convertor that has been on there a loooonngggg time. did they come with this originally or was this maybe a calif car,?? i don't have vin handy. i figure to drop it anyway.
