No, I'm saying my 1946 half ton pickup, then use a complete 54 or earlier PASSENGER, torque tube assemby. The passenger rear end is the only 3:55 ratio torque tube around and now getting difficult to find. Now, non of these individual passenger pieces will fit in your truck axle/torque tube so you'll need to swap the entire unit including rear end. I wanted to have 6 lug wheels so I took this 54 torque tube, tossed the 54 axle assy (5lug) and installed into a 48 chev passenger rear end (6lug). This intire unti went under my 46 half ton pickup. I didn't have to shorten axles or anything except modify the passenger mounts to fit the trucks rear springs. The pivot/mount with a torque tube rear end is critical, needs to flex and must not be made solid like an open drive line. Difficult part now days is locating the 51 to 54 torque tube from a powerglide equiped car for the 3:55 ratio. This is realy not a difficult job, no more so than going open drive line. Best of luck.
