Linda,
Never heard of one breaking, but I suppose they do. I haven't worried
about it
-- they're not heavily loaded, nor do they move very much. Still,
everything
eventually fatigues...
My recommendation: Don't bother unless
you're taking the distributor apart for
other reasons. If you have never
dismantled your distributor to check and
lubricate the weights under the
breaker plate, you should do so. Can't tell you
how many cars I have found
with gummed up mechanical advance mechanisms.
Replacing the springs at that
time wouldn't be a bad idea, although I have never
done so.
Gary

Hi Gary
Just wondering about replacing the springs, rather than waiting for one to
break. Anyone do that?

As Paul indicated, all you need is the 7.5 cam and springs. I
