What the heck??

042634-01 is the part number for the rear frame on the Stun Runner yoke (the part that bolts to the cab) See pg 40 of the
manual. (SW yoke uses an A040236-01)
The picture above shows 042634-01 painted on the
front frame. (the part that turns)
Front frame on Stun Runner and SW should be P/N A040247-01 (mine is painted on the inside under the spring)
The crosspiece looks different from the one shown on pg 39.
Hmm. . . . Curiouser and curiouser.
Some handles only had the two screw holes like your picture above shows, with no hole for the roll pin mentioned in the manual. The screw holes are spaced the same on both versions.
