Please take a look at the photo below. Its from an ebay ad and claims to be a full Powerflex front and rear bush kit for an E36.
This is the inclusion list. Notice there are 6 un-numbered bushes at the rear that are not included and item no.3 for the front suspension is also not included. How can this be a full bush kit - do the missing items not fail and never need replacing or something?
