Went to jack the car up using the original jack for the first time.
Im convinced that the jack is the wrong sort, the top is almost flat with sort of chamfered sides if that makes sense. It looked very unstable when positioned under the jacking point (which has a hole there), I know some 172 owners have had their jacking points collapse. I would have thought the jack should have some kind of pin or something that engages in the hole?
What sort of OE jack do you 172 owners have?
