This shorter rear hose (160mm) is fitted to late model Mk2 Golfs with drum brakes (approx. 1988 - 1992). The earlier longer hose doesn't fit these later cars. These hoses aren't as common and can be pricey, so it's worth having a spare as they sometimes perish slightly or develop a bulge for no particular reason. I've always found Meyle products to be good aftermarket quality and they last well.
