1996 A8 4.2 PF - service - what parts are the best?

[gti69]

I was told by the seller that these should fit my A8

Front:
BOSCH BP402

But I think this is more appropriate as the year matches - part number is the same though:

Not sure about the rear ones though at all.
Rear

Guy says this should fit:
BOSCH BP783
http://www.ebay.co.uk/itm/3507047281...196%26_rdc%3D1

But I reckon this might be this one?
BOSCH BP617
http://www.ebay.co.uk/itm/Bosch-REAR...item43b846ae80

Any ideas how to check exact Bosch part numbers?

Thanks.
