I started putting my suspension bits together this weekend. I've been bead blasting, painting and assembling. I have an '85 Carrera front end with boge struts and I had a set of 914 Koin reds (adjustable) that I wanted to use. Unfortunately, they don't just bolt in. I machined up some step spacers that allow the Koni to be used with the Boge struts.
The Konis have a step at the top of the cartridge and will swim in the Boge cap.
Here's a pic of the Koni top:

Here's a pic of the spacer I machined up. It sits on top of the insert and the outer diameter is a perfect fit to the strut cap.
