Great product as always from Duff. However, after 4 months I’m still waiting for their early bronco catalog….

I have to admit that the twin stick billet knobs I ordered are not for a Bronco but a lifted 65 Chevrolet 3/4 ton 4×4 truck. I confirmed the size needed and found this web site. They look great and now I have the shift pattern on the knobs.

Perfect for our 1969 Bronco and a local machine shop tapped the shifter knobs to match the shifters. In fact, once they saw the Bronco, they did the job for free! Another great product from Duff!

I purchased the billet shift knobs for my trans and transfer case and they look awesome. Like mentioned I had to frill and tap one to fit my trans shifter but it took all of 5 minutes to do. Great product and looks so much better than the 40 plus year old plastic knob that was on my NP205 shifter.

I have been looking for some new shift knobs for my Atlas shifters for many years now since the pattern on the original plastic knobs wore off years ago. I looked everywhere for new, round knobs and then finally realized Duffs had exactly what I needed. I had to drill/re-tap the knobs to 1/2-13 threads but that didn’t take very long. Now I’ve got some nice aluminum knob s that will NEVER lose their shift pattern markings and they really dress up the shifters at the same time. Top quality and highly recommended!
