I have a scanned page from the Hayne's manual (1992-1995 Civic and del Sol) which I can send to you. It shows the distributor assembly. It might be item 3, 4 or 7 in the diagram. You will have to remove the entire distributor assembly. I once had to remove the entire distributor assembly to get at two gears that were squeaking inside. I sprayed WD-40 inside an it's still going strong. The gears I believe controlled the TDC sensor.

Point being made is, these things are probably bullet proof and you could save big money by buying at a scrap yard or something like that.

Hope this helps.
