SHIFTER MECHANISM IDENTIFICATION
All factory (original equipment) Mopar/Hurst 4-speed shifter mechanisms can be identified by the four digit number on the reverse lever, which is the longest of the three. 1968-75 A-body and 1968-69 B-body uses #6353 (as does the later truck overdrive), 1970 B-body #7174, and 1970-74 E-body/1971-74 B-body #7180 (which happens to be stamped upside down). All of these have 5/16" holes for the reverse linkage rod attachment. A common Hurst aftermarket/replacement shifter mechanism (for most A & B applications) has #6370 on the reverse lever, and utilizes a 1/2" hole and a reducer bushing.
The 1963 T10 Borg Warner Hurst mechanism reverse lever is #2041, and the early 1964-65 A & B-body Hurst mechanisms both use #2336 reverse levers, which is stamped on the right side instead of the left. However, the shift handle stubs (where the Hurst handle bolts on) is different on these two mechanisms.
1966 through about January 1968 production, Ma Mopar used an Inland shifter mechanism and shift handles, which are easily identified by the reverse lockout "T" handle, and the unique teardrop shaped shifter knob.
Two different shift handle attachments have been used on the Hurst mechanisms. The early mechanisms (1963 T10/1964-65) use a solid shift stub that is drilled and tapped for attachment bolts. 1968 introduced the slip-in (or bayonet style) handle attachment, and was used until some early 1971 applications. To remove these handles from the mechanism, a 010" feeler gauge is inserted between the handle and the stainless steel retainer on the driver�s side, which releases the locking tang from the notch in the handle, allowing the handle to be pulled out.
In late 1970, some applications switched to the bolt-on style handle attachment. The first style is similar to the early bolt-on mechanisms, as the threaded anchor is on the stick bottom, and the bolts pass through a small plate to clamp the shift handle into the mechanism. On later bolt-on style mechanisms, the holes are in the stick bottom, and the small plate has the threaded anchors.
Spacing and length of the three levers are unique to each style mechanism.
