So my grandpa who lives across the street from me bought a 1970 arctic cat puma or panther 634. I'm not sure if its a panther or an puma but he bought it brand new back in 1970 from the local arctic cat dealer. It has 800 original miles on it and it has sat in his garage since 1978 and hasnt been run since. Its real dusty but if cleaned off it would look mint. What do you guys think it would take to get running again? I really want to hear this beast of a sled. My grandpa told me its a loud SOB. and plus he wants to restore it. so what do you guys think?
