I asked that same question when I emailed him, but he realized he got them from DOR which is extinct so don't get any hopes up. Looking at the pics of the DOR mounts, they look very similar to the ones BigmeatVX fabbed himself. That makes me feel better, and I think I may be attempting this tomorrow morning. I just finished doing my HD tie rods, with pics to follow soon. I can't believe I used the wrong tap when tapping out the first one though. I knew I should have put it away, but I forgot, and ended up threading about 3/8 into the rod. Fortunately I still had to chop 1/4" off of it and had some titanium putty lying around to fill in the few threads remaining. So they will both be finished tomorrow morning after they get powder coated.
