I ended up getting the M1 Abrams.
Great knob, very impressed with TWM.
Always loved my arc knob, so this really brings back memories.
I didn't bother with the zip-tie, I used a small piece of Double Stick Mounting Tape from Canadian Tire to stick the inside of the ring of the shift boot to the shift lever. Looks great when the boot stays flush with the knob! Lol
