For one car you need:

3 of #9796
2 of #9799
2 of #9798
1 of #9795

So double those quantities to do both your B4 and T4. You have to be careful when distinguishing between the "short" and "long". The black ballstuds that come with the kits are the "short" version, and the silver ballstuds are the "tall." The "tall" silver ballstuds (9796) are used on the front shock tower, rear u-brace, steering blocks, and steering bellcrank (9795). The "short" black ballstuds (9799) are used on the caster blocks, rear hubs, steering rack (9798), and servo horn (9798).
