After owning a few tamiya's, I decided to mounted my TRF shocks the same way to my MI2. Just get the 5mm florine coated ball nut (TAM53599), and flourine coated ball stud (TAM53598). The ball nut mounts on the shock tower with a 3mm srew through the back to secure it, use a few spacers to get your shock as verticle as you want ( if you look, actually the MI2 stock mount has some angle to it too). the threaded ball stud has the same threads as stock so all you do is replace the stocker with the 5mm stud. I built my shocks with the included tamiya plastic shock shaft ends (short), and it turns out beautifly. You can get the non-florine coated studs/nut as well to save a few $$, but they sure do make is smooth as silk, plus you get 10 in a pack.
