I ended up going a different direction, I got a ford/mustang based shifter from the Kirkhams and I really like it. The good folks at ERA even took care of my picky nature and agreed to take the Hurst one back, they are good people
The mustang shifter may not be for everyone, it's kind of a quirky design. But the reverse lockout works as designed and it's very original. It uses a rebuilt mustang shifter body, modified handle, hiem jointed linkage with aluminum shift arms. Pretty slick.
Thanks, Chuck
