I was wondering if the internals of the Non-vented opti are the same as the vented opti? I have an Non-vented Opti with a broken mounting tab but very low milage, and I'm wondering if I should save the internals in case my Vented Opti ever goes bad?

Thanks,
Rob

 

Not the same.. different bearing, etc..
Cap and rotor are similar tho..

 

Cap and rotor will interchange, I have vented cap on my non vented opti now.
Drive mechanism is different, I am not sure if the optical portion is the same or not, I think they are.
