Bill,
if you have two tires that you want to keep, buy the other two to match in
size.
I assume you have rostyle wheels.
Original was 145-13.  People often install 155-13.  This is a little
higher, will give you more sidewall flex, throw your speedo off a tiny
bit, lower your rpm on the highway a little bit, but might look ok on a
"ridin' high" '77.
165-13 makes the car look like a tractor.
165/70-13 is a good choice.  Same diameter as a 145-13, but a little
wider.
There are some other choices, but they are more for a performance-modified
car.  165/65, 175/60, 185/60(again same diameter).
