Gene Berg 4 Speed Shifters Pre 1960 bus shifter RHD
As GB 6746, however, for right hand drive. Polished T as standard, subject to stock levels. Pre 1960 bus shifter. Chassis number up through 501706, ball diameter 15.7mm. Polished inset T handle as standard subject to availability. Approx 22" tall. Please note that you should always check your ball diameter BEFORE ordering as we are seeing a rising number of cases where previous owners have replaced the stock shift rod with the 60-65 one. We are able to make a hybrid shifter for this, as neither the GB 6746 or 6748 will work correctly. SW #5  
These shifters now have a Silver T Handle as stock with all other handles being upgrades. (as below)
