The agents want more than R1000 for the rear pad set

Ferodo only does pads for the front (Ferodo part number FDB1577)
There are locally manufactured pads (Safeline) that fit. Does anyone have experience with these? Are they any good? From their online catalogue (http://www.safelinebrakes.co.za/brake-p ... tml#Patrol), it seems that there are two possible sets of part numbers:
Patrol 3.0Di (All Models) 2000- Front D3384, Rear D3386
Patrol 4.5 4 x 4 S/Wagon 1998- Front D3382, Rear D3383
Patrol 4.5 GL, GRX (All Models) 2000- Front D3384, Rear D3386
Does anyone know whether my 1999 4.5E GRX with disc brakes all round will take D3384 and D3386 or D3382 and D3383?
I also found pads that will work in the REMSA online catalogue (http://www.remsa.com/catalogo_pormarca.php). The REMSA part numbers are 711.04 for the front pads and 317.12 for the rears. Does anyone know whether the Spanish REMSA pads are available locally and where?
