I have an All Star TAS827FR 6'10" baitcasting rod.  The center piece of the top eye popped out.  I was wondering where I could locate a replacement inner piece for the top eye.  Thanks for the help!  

Replace the entire tip guide, the inner line guide is not available nor could you successfully press one back in and expect it to hold.  Walmart sells Fuji tip replacement kits for around $7 or so.  3 sizes of tips.  I'm betting that rod will take the smallest size.  Instructions are included.  

how would i get the original tip off?

Here, try this thread from a couple of days ago.  Should get it done for ya.  Goodluck-ff15
