Default rear main seal

12 valve motor, I was working on trans and decided to replace the clutch while I was at it, which led to a pan gasket and a rear mail seal . Problem is, somebody already replaced the rear main and installed a new wear ring on the crank and I don't think there is any way to get the new seal on the ring. Is there an oversized seal made to work with this. I have a felpro kit bs40650. the old seal says D HK 3925530 and is noticeably larger inside. It seems I have three options, put old seal back in, stretch new seal over the ring, replace crank, or find something that fits, or remove the new wear ring and hope the crank surface is good. I know, that's 5. So, what would Max do?
Any help appreciated.

I would buy another kit from cummins that has the seal with the wear sleeve. You can either replace the wear sleeve or clean the old one up if its not worn too badly.
