I have a set of 400E calipers that I rebuilt and getting the boots on were a PITA! I ripped 2 and had to buy them again.used silicone and it still took hours just for the boots. Finally got it done and put them on the w201 and the stock rims wouldn't even clear them. Lol. Now I have them sitting until I get some stock 400E rims. I would probably go with the rebuilt option. That way you won't spend time trying to clean everything up and buy all the parts and if it's defective you can return it as a whole unit.
