Is the pan (refector) different from 121 and 105?

I just bought a superdish from an online auction and it showed up with the pan all dinged up.

Is the pan the same for the 105 and 121? I found someone selling pans from 121 kits and was just wondering if they were the same.

The kits are the same except for the LNB.
