Speedo cable for a T5?

[19GMC63]

While I'm waiting on my driveshaft (should be here Monday), I was looking at the little things like a shifter and speedo cable.

What style speedo cable should I be looking for? Is this exclusive to a F-body or can I get one from any GM car? Would parts stores carry these? I did a search on ebay for "camaro speeometer cable" and found one for like 35 bucks... no thanks.

Here's a pic of it... it has a retainer of some kind, don't know what thats all about.


My shifter came in yesterday... can't wait to put this thing in and on the road.
