I am super excited about the T jet's come back like you boys. I am on the verge of signing the deal. The only thing that is stopping me is the 20mm extra GC that it has now. I prefer the 2010, 170 mm GC. How tedious is getting the old GC back? I believe it involves other modifications like the suspension if GC is tampered with. And guess I should get it done outside separately and I am worried if it can be done like a factory finish.
