The seriel # 781019 Model #149730100 How do you figer out the year of M.F.G. for this ? Yeh I did check the rearend bolts and some one along the line did put an extra brace on the right side . I figured the bolts have been lose at one time . That tranny wont be used except for parts . I have a plan for a special build I have been collecting parts for, for a long time know . So I plan on using a manual tranny . I will post the build as i go . Thanks Bruce S.
