Crown Imperial Cotswood In Frame Cabinets and Drawers - Help Required

To save money I have installed most of the new kitchen myself and it looks very nice. However, I am stuck on a couple of points and the instructions received with the flatpack / online are useless:

1. How to fix the drawer runners on the 1000mm base unit - when attached directly to the carcass the runners do not slide past the frame so I must be doing something wrong.

2. Where are the soft-close door dampeners meant to be installed?

Your help much appreciated!

1000mm unit has a frame? then draw runners will have spacers or stand off the sides to pass the frame. what type of damper do you have?

I worked it out! Clipped 2 rectangular spacers together for the runners so now the drawers are installed.

The soft close doorstops screw into hinge holes on the opposite side of the hinges, again courtesy of some spacers.

Job done.
