hi all i've done the usual search but there is no clear answer. i realise that the vw alhambra and sharan linkages are the same but no reference to interchangeability please help. I have the dreaded sticking wiper issue, tried freeing the spindles only to have the housing shear from the assembly, so my question is this can i install the 4 bolt version into my car which is a 3 bolt type, having great difficulty sourcing a 3 bolt complete unit for reasonable money, but able to get a second hand 4 bolt set up pretty reasonable but no returns. Has anyone changed them over? as the 4 bolt looks like it would fit obviously adding the extra bolts but will the scuttle trim hold the spindles in situe without disstorting? 99 v reg tdi
