Tail Link - Liner

[D.A.]

My Parts Manual calls out the "Link" as part number 14180-02. I did an internet search of the P/N expecting to find numerous options to buy but there was NOTHING popping up. I finally brought up Univair's website and searched the number and their own unique number came up for it. I also searched their site for the 86062-80 Liner and noticed their's is un-drilled. Is that how the liner tube comes, un-drilled?
So, my question is, where do y'all recommend that I buy the link and liner and is there another P/N that I'm unaware of (Not shown in the Parts Manual)?
Thanks in advance.

The liner is precision ground and chromed. Univair or Dakota Cub.
If Experimental, try Javron.

They come undrilled.

All the stabs were hand drilled on the airplane.
