I changed to Volvo Girling and vented fronts and 320 drum rears.
The brakes all worked prior to the swap but i can say they work better now.
One set of calipers and drums came from a car i parted out.
Also...I have a whole other front rotor/hub as well if you are interested. It came off the parts car and is also -FREE

Preference will go to anybody who will pick up the entire batch (and give me a 6 pack of beer hahaha).
after that, i'll consider breaking the batch up...
and then if i still have them, I'd consider shipping them...
