I've used MGW for years and years, I have one on my GT500 and just installed one Saturday on my sons '12 mustang. They are perfection in design & quality. I've always bought them direct & they are awesome to deal with, personally I'm considering for my Gen4, if I do, I would go thru Mark, that AI bring benefit to MGW & Mark, who's a great community supporter here .. and has them ready to go. But that's just me.
I did have one once where I went with a very short lever & it was too short, not due to effort but my big ole fingers could get smashed between the ball knob and the shifter ring, but I have big hands. (and we know that means, ladies, big ... gloves). A medium length lever is butter, super short pattern, perfect preload, great height for comfort. Yep, I'm a fan.
These are a little bit of a PITA to install, like on the mustangs, the install is a in the car under the car in the car under the car routine, but overall, even a caveman could do it.
