I ended up just buying the individual pairs of 3racing ti turnbuckles. What was really annoying is they have the same part number for the ones that use a 3mm wrench and 4mm wrench. So now I have some that are 3mm and some that are 4mm. So stay away from the individual pairs and get the whole set.
I'm so tempted to change them out to the set.
It shows the TBS-FGX/V1 turnbuckle set as available on their website.
