yes,iff you see on all fiat 1500/1300  1966/1970 berline original on front idem on a 1000 TC

Peter,
          It would be nice if they were.Theo (the seller) sends you Rover or Volvo calipers (with bleader holes at the bottom !) instead of the correct Osca ones.It is very important that you figure out if the calipers will go in the front or the rear of the wheel so you can figure where the fluid lines should go.
Theo wanted me to run a line outside the caliper from the bottom left to the top right,something I hated the thought of.One good rock and the line could easily have been damaged.Girling limited the amount of external lines to an absolute minimum which sounds much safer to me.

thanks grant, basically it is just to improve somewhat the brakes of my BS1 1600...on the front as i will leave the rear as they are...
