The whole point to eff marry kill is to make the decision a tough one. Like all three women are very hot, or all three are rank. Pam might be past her prime but she's still semi bang able, at least compared to them, lol.

Nice that it has room to fit it that way . The cougar and yoko do it the same way as well and still look slimmer than a b4

I used the hammer and pinion method to knock the pin out. However, how to get the rest out once the end of the pin is flush with the ball? I do not have anything 2mm which is strong enough to take the hammer.

Default Tebo's RB6 wiring
rcinsider.com posted a pic of Tebo's RB6 from the CRCRC race. Looks like he's made a few changes since the last time I saw his car. He appears to be running the full-size RSx Response servo with the Alu top now, instead of the One10 low profile and he's slid the battery tray all the way back.

Your steering rack is on backwards...
