For turnbuckles you can use Ti tc3 turnbuckles they all must be 1-1/8" and you will need 6

But i used the steel ones and work just as well because they are so much better than stock and half the price of Ti. Oh and the ball cup you need are racers edge they fit right onto the stock studs. You can get those and the steel turnbuckles thru stormerhobbies.com for about 20 bucks or so.
