rod tip replacement?

I have 2 rods that need the tips replaced. The liners(I don't know what the correct term is) of the eye on both rods have popped out. All the kits you buy the tips are too large. The rods are both BPS microlites,one is a 6'6 ultralight and the other one is a 7' light. If anyone knows what size tips may fit these rods I would appreciate the help. Thanks.

Take a micrometer and mic the end or the rod then go to Fishing rod tip tops, fishing rod tip repair and select the style and proper size. Big selection and all sizes.
