I have been running my 62 for about 10 years now. Not a lot of miles, but a few times a year, I make 120 mile highway trips. I havent had a problem. I max out at about 55-60 mph - its a k-20. I would say keep the oil level up and the input shaft bearings fresh. They make a "high oil level kit" which is a street elbow that goes where the fill plug is. Let's you keep the oil level about an inch or so higher. I'm not running one, but plan to. I think the problem is they leak, and when the oil gets low, they fail. Good luck with yours.
