I&#039;m a high school student and am restoring a 1939 70 for FFA.  I need to find new o-rings for the cylinder sleeves.  It is a three gear motor.  I also need to find new &amp;quot;snap rings&amp;quot; for my rear rims. Any help would be grateful. Also, the transmission housing has two small cracks between bearing races in the front, along the factory casting joint.  Should I try to fix this?
