Second question... If I got just the differential lock parts from a L175 junk yard tractor, could I convert this thing to having a differential lock? I see the plug in the casting where the lever goes and not having a diff lock is killing me haha... I'm just curious if the entire rear end assembly is different or if they just added a few pieces that I can scrounge and put in there... also, if this is the case, would L185 and L245 parts work or is it only L175?
