now fella ,
i dont think theres anything else in the ford range that will fit the mk three
imo the best thing to do would be to remove the flanges and take them to a local engineers and have them welded up and redrilled to 5x108 , youd have to see if theres enough meat on them for 110 ,
or , depending on the offset of the wheels your looking at , have them machine you up custom 10 mm spacers .
hope this helps
