If you need parts for your LA .46's and no one here has them email O.S.. I got enough parts to build two .46's. I used parts from some LA .40's and had some piston and liners from Tower. e-info@osengines.co.jp This will get you in touch with Mr. Wen. The parts are in OS packaging and the service is great. I got two crankcases, two cylinder heads and two piston pins. The rest came from the .40's and stuff on hand. 9700 Yen total with shipping. About $95.00.
