Speaker size..a body

Hey I was just wondering about the natural speaker sizes in a 73 scamp


From what I gathered backs are 6x9 and have no clue what the front is...4X10???? Idk could use help


Are most a body’s using same ports

In our 70' Dart we are running the 6X9's int he rear and just purchased the Retro sound 4X10 for the front. That actually has a left and right in a single speaker. I can't wait to get it in and see how it sounds.
