I hate to say it and I'll put the flame suite on for it. EVERYTHING should be metric!! I fvckin hate SAE! Lets see if a 10mm is too small grab a 11mm done! None of this fraction crap. At the very least build the whole damn vehicle with one or the other! Not half and half. Bi-polar assembled cars are like dealing with my wife!! LMFAO and trust me thats enough!!
