I just bought some hockey pucks, and after some very messy time at the grinding wheel I have shaped one to fit the alt. jack point in front of the official jack point. I think the reason it was bending is because it was metal on metal. So the puck may help.
I will also try the rear point just behind the muffler. I just want to check and make sure nothing will get bent/damaged using that point. I might shape another hockey puck for that point instead of using a 2x4".
Thanks!
