I just went out to the garage and looked at my 149 and 169. Mine rides right in front of the drain plug. It would hit if the motor was forward or the axle was back. If i remember right the 1450 i had looked just like these. Here are a few pictures. Dont know if it will help or not.
Like Matt G. said mabey the C-Channel just needs squeezed back together.
