<VV> Sluggish Convertible Top

[Steven J. Serenska]

Group:

The power top on my '65 convertible has gotten quite sluggish of late.  
It's gotten to the point where I have to reach back and push up on it 
with my hand to get through the initial stages of the "up" cycle.

My question is, is there such a thing as "progressive weakness" syndrome 
for power convertible tops?  Can I expect this problem to continue to 
get gradually worse?  Or should I be concerned about a sudden stoppage 
of the top in the near future?

My dilemma is whether I should fix it now and not risk it getting stuck 
in the open position during a rainstorm, or whether I can wait a little 
while until the offseason when I'll have more time/money to do the work.

Finally, are there specific parts I should be thinking about replacing?

Thanks in advance for everyone's comments.
