It sounds like your forks are due for a rebuild if the rubber stops are gone. I was swapping over two the brembo front brakes so I never rebuilt mine. They were making the clunk sound pretty bad and I was thinking that it was handling pretty bad. I did leave my brembo front forks stock and simply rebuilt them. I also replaced the steering bearings while I was there and aligned the forks when I was done. The handling difference was amazing. I do not think the forks improved that much from 77 to 82, so I think most of my handling improvement was just having the front end work properly. You might try it before spending big bucks.
