Tamiya gear diff or Spec R for 416/417
I am interested to buy a gear diff for the 416, but it seems i have the choice of buying Spec R or Tamiya Brand. i seem to notice that the tamiya brand is a little cheaper. What i want to know is , are both brands 37T or 38T in pulley size. also which one is more leak free and durable?
Your input and experience is very much appreciated.
