Re: Transmission lineage
John, I’m very sorry about the phone communication issue yesterday....in trying to put you on hold I inadvertently disconnected you and was then stuck on two more long calls.
We were out of the 39 clutch arms so you had okayed the installation of a 1933-34 arm on your transmission. At the time, you still didn’t know what clutch/pedal assembly you had so we were guessing at what might work. As you have now confirmed that you do have the actual 1939 pedal assembly on your pickup truck, ideally you should have a 91A-7511 clutch arm. The 33-34 arm we installed is very close in its angle but is about an inch longer.
So, yes, it could affect the geometry of the linkage. If you can locate the correct arm, it’s fairly easy to swap these arms, as long as the transmission is still out of the vehicle. Let us know if there’s anything else we can do to help out.
