Ok, I've read all I can (archives etc.) and am still confused...

[feelstranger]

Sorry to bring this up I'm sure but,
 I am confused -
 Were UFO's replaced with the earlier 5K /89-90 200 brake system or were
they replaced with the later S car system and/or is there a difference?  The
caliper is the G60 - ok but -Is the rotor the same?  Are the pads the same?
I have the work order for my car - ufos replaced in 1993 at 22K miles with
"brake Kit -   441 498 615"
The local dealer told me that this number is no longer valid...
He also told me that all the numbrs in the parts list for the modified cars
reference to the later S/A cars for both the rotors and pads - not the 5K
Whats the deal here?
TIA!
