These fit the MODERN Torq Thrusts ONLY...I'm only showing them on an old TTD below because I don't own any of the modern wheels.
Here is a cool set of four billet flat caps for modern TTs (I believe these are for the 2.25" hole-to-hole spacing). I bought them thinking they would fit the old style 2.125" bolt spacing TTs but no dice. As you can see from the pics, they would have looked extremely cool on the old TTDs, but they will definitely dress up your modern TTs and make them look a little less 21st century.
The guy I bought them from claimed to have had them milled by a local machine shop at great expense, but who knows. Selling for $50 shipped which is what I have into them. They need a polish but are otherwise in excellent shape. Includes stainless fasteners - I think all 20 are accounted for but there may be one missing, I'll check.
