1. yes you did. 2. I said as much when I said Z1 discontinued their own product 3. Ive had a 3" on my TT when I got it, still do. Frowning or not. 4. Coz's rails ARE junk. They had crap threads and did not have proper AN seats. His solution to this was to epoxy the fittings into the place. When a Coz customer asked 300Degree about a leaking rail it became obvious that the rail was a counterfeit. The rail was NOT a genuine 300Degree product.
