1950 Ford car slip yoke exposure

[Don T]

This car did not come with a driveshaft, I "found" one and installed it and now am wondering if it is too short. The pic shows I have about 1-3/4" of the yoke barrel out of the transmission tailpiece, should the yoke be deeper into the tailpiece? This pic was taken with the car weight on the axles. All new motor and trans mounts as well as new rear suspension bushings. All the other parts of the engine, trans, diff are original to the car. Thanks for your thoughts!
