im building my 31 roadster and seem to run into an issue. The car was an abandoned project and I’m not sure exactly what parts were used to start the project. I have a stock frame with a Tardel 32 k member,39 trans, 50 flathead and a closed banjo rear. The torque tube seems to be too short by about 2 inches when I try to install the motor and trans into the crossmember. Do I need to move the rear forward of the rear spring? Do I have the wrong rear and torque tube? Thank you for any help with this.
