1990 Civic Distributor

My wife has just bought a 1990 Honda Civic and was told it needed a distributor. Would anyone like to shed some light on how these are installed?? Is it a tough job or not? I beleive it's a 1.6 engine...not totally sure till tomorrow....i know it mounts on the passenger side of the motor from I had seen. Thanks.

remove 3 12mm bolts. unplug harness. pull out. installation is of reversal.

then do this

Do those distributors go in only one way???? I know some cars can be 180 off but they will just backfire....you take them out and do it again.....

Yes, the distributor can only fit the notches one way.
