[TR] TR3 frt. brake dust shields

[Angelo Graham]

Hello List:
Just wondering how many TR3 owners are still using the dust shields 
on their front brakes? Are they really necessary? Can understand why 
competition prepared '3s do not use them, but how necessary are they 
for street use?
Trying to piece together a front disc set-up and many of the dust 
shields I have found have broken mounting tabs.
Thanks for any insights.
