I'm wanting it for my 58 GMC. Larry

It can be identified by the 7 bolt side cover. It also has a fine spline output shaft. You will need to modify the shift arms and find a fine spline yoke to use it in your 58.

I'll also have to source the speedo hook up. It came with an extra starter and the bell housing which I don't need, plus the clutch lever and a clutch and pressure plate.Larry

I recently bought a 1969 3 speed for the floor shift linkage. Is my 1969 3 speed synchronized? What year did they start synchronizing 1st gear? | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | 67 was the first year for the full syncro 3 speed.
