TR rotors - interchangability

[Angelo Graham <a3graham@mc1adm.uwaterloo.ca>]

Hello Listers:

Anyone know if TR6 front rotors will fit on TR3A or early TR4 hubs and
accommodate the caliper?  I know the diameter and thickness are the same
spec., but not sure about the wheel bolt pattern.  I seem to recall that
somewhere that the pattern is the same.  So, anyone ever tried to fit TR6
rotors to a 3A?  Should it work?

Thanks in advance,
