I ordered a set of Hipshot Ultralights with mini clover keys for my Classic IV. These are specifically made for T-Birds and they don't list them on the website for some reason, so you have to call them to place an order.
If you do order them, make sure you talk to Jason first. I initially emailed them to ask about availability/price and Jason quoted me a price of $100 for the set, but when I called to place the order, Oscar tried to charge me $35 per tuner. I'm sure it was honest mistake, (I had to wait another day to order while Oscar verified the $100 price with Jason) but you never know.
