I run the Mr. Gasket vertical gate, aka Hurst V Gate 2. It has a bolt-on set of stops. For the price, the Long darn sure ought to have stops. Apparently it does:
Designed exclusively for G-Force G-101 clutchless transmission.
Allows transmission to be rotated 90ยก for increased ground clearance.
Supplied with stainless steel tube rods and Heim-end linkage for all applications.
Push-pull design virtually eliminates missed shifts.
External shift stops prevent overshifting which can result in transmission damage.
