There is a dedicated Murray Tractor forum run by Murray owners https://www.tapatalk.com/groups/bbymurrayarchives/index.php?sid=71393d39e85e2521408b988bcb2c673e
That would be my first place to look.
They know the places that have supplies of old parts or how to work around parts that are no longer available.
Nothing on the deck lift mechanism is particularly difficult to make with only a hacksaw & file and access to a welder.
