Posting for the possible benefit of others .
Tried to find a listing for rear disc rotors for my 97 300TDI 130 , could not find a correct match .
Mine are 298 x 70 x 14 , which are only listed as fronts everywhere I tried . One helpful fellow found them listed as rears in an old catalogue .
The ref. no. is 087 for the above size .
Hope this helps anyone else who needs them .
