I used to own a Civic VX. The ISB in the transmission exploded, destroying the main shaft and the bell housing. All of the gears, including the diff are in excellent shape.
If you've got a D-series tranny, some of these gears may be desirable to swap in.
The ratios are:
1st: 3.250
2nd: 1.761
3rd: 1.066
4th: 0.853
5th: 0.702
FD: 3.250
These are not quite as long as HF gears, but still excellent for mileage. Make me an offer on the parts you want. The countershaft is still assembled and I still have a few other tranny goodies left:
