I've made the measurement below on the Spohn mount, which is 13/16. What's that measurement on the Founders version?

I measured in the same spot as you did in the same fasion. The founders are angled on that side. Reading from the bottom of the tape measure its 3/8, at the top its 7/8. Hope this helps.

Manufacturer pics make the slot and the outside edge of the mount appear parallel. Any chance of a pic?

I'll be able to get you one tommorow when I'm working on the car.

I just realized I looked at your pic wrong. I measured the correct side which is paralled and its exactly 5/16. I left my phone at the house so no pic :/

I figured the distance would be smaller than the Spohn version--but I'm surprised at how much. No need for a pic. Many thanks for your help.

Yeah there really isnt much there, pretty much the same story on all 3 slots. No problem, I'm always by the car.
