1989 Mitsubishi excavator ms180lc looking for parts source
Caterpillar bought Mitsubishi in the early'90s? and used them to start their E model machines. The first machines were basically Mitsubishi painted Cat yellow, when they came out with the B series they made significant changes. You might try them otherwise I don't think there's much out there. What are you looking for? I've probably still got a service manual for it if you're interested.
Might you happen to have an operations manual for the Mitsi-180-8? Thanks, Kcor
