hey guys, i just acquired a (what i think is a 1954 --7514--7.5) with the broken shock absorber spring and it pushed the center out of the lower water pump housing and bent the wear plate, messed up the keyway in the impeller also .are these parts expensive and where can i get them? also this motor has what i think is a 1957 engine couling on it, the tag on the clamps claims 7514 which is a 1954 is there casting numbers on the block to tell for sure what year? i am trying to locate 2 pull rope guides that protect the rope from the clamshell couling. thanks mike 540-379-1113
