I am replacing the Front Upper Strut Bearings on my 2016 VW Golf R. There are two listings for that part on the DAP website – both made by VW. 5QM-412-249 and the 5QM-412-249F. The first is about half the price of the latter. I contacted DAP and they didn't know the difference and recommended the 249. VW Parts Center has a different part number - 5QM-412-249E at a price between the two listed at DAP. Is there a real difference between these three and which would you recommend?
