Civic: this is the later version (about 1975-79) that fits inside the shifter extension rather than over a lip at the bottom as per the earlier version.
As there has been plenty of chopping and changing of parts over the years you will need to stick your head under the car and examine the underside of the shifter mechanism to see which type you have, although this version is far more common than the early one.

Accord and Prelude: All ones of the appropriate year should use this type of boot.
