I own a 1978 Mercedes 540 SL.. I was replacing the gearbox as it leaked fluid, I found it also needed the steering coupler and found a new one. Now how the heck can I hold the 75 puond hunk of steel above my head and align the bolt holes as well as aligh the coupler with the steering shaft splines? I only have two arms. I can't seem to find much in repair manuals to outline the process. Pardon the pun "I'm in over my head" does anyone have any advice on how I can put all things in place. PLEASE ADVISE, Thanks David..
