@Marcel posted:A word of warning from my side: I needed a new steering coupler, and seeing that plain black rubber was the same price as the red racey urethane thingy, I opted for the latter. Progress on my build was (is) slow, so when I accidentally touched the mounted coupler a year later, it actually crumbled to pieces. Basically fully eliminating the coupling between steering box and column. When driving this would likely have resulted in more than just a scratch.
Lesson learned, and I duly bought a boring black OEM Made in Germany rubber....
NEVER NEVER use urethane for a steering coupler. Always use a cloth-rubber "rag joint". We've been warning of this since the SOC site inception.
