No extra parts. The inserts that you pull out of the Boge struts will be very, very different from the Bilstein inserts, but it sounds like you may already know that. The only things that I can think of that make the job easier are:
1 The lower bolt for the shocks can be really tight. I just put a piece of pipe on the wrench to break them loose.

2 The top strut nut can be a pain unless you have an impact wrench

3 It would be nice if Bilstein included the special nut tool for the collar that holds the insert in. You can get one for free by calling Bilstein. You can probably manage with a set of channel locks, you just won't be able to torque the thing to a specific torque that way.
