Last fall I purchased a john deere 450b. This spring I went to use it and the LH final drive unit failed. The s/n on the crawler is 180490T I belive it to be a 1970. Do to the extent of the damage I am in need of the entire assy. If anyone has one or knows where I might find one let me know. thank you Aric
