Decided to put the rear Riddler on. Don't know if the 513's will arrive in a week or a month, so I just decided it's better to bite the bullet and do it twice instead of risking another peal-back in an already weakened area.

The damage from the inside:



The new cover:



Bring on the rocks!!

Nodular cast iron. "Nodular" means the iron is ductile, i.e. more malleable than regular cast iron (had to look it up). Supposed to take a lot more abuse than regular cast iron.

Do these coveres require more gear oil than stock? I am thinking of changing them out when I do my first gear oil change.

You certainly could because the fill hole is so high. All you will do is spew nasty-smelling gear oil out the vent tube.

Everything I read said stick with the recommended amount, so that's what I did.
