Subject: Re: Lg45 power steering conversion ?
I have just fitted an electric power-steering mod to an E Type I am rebuilding. It's not on the road yet so I haven't tried it out, but everybody speaks highly of it. I think it was supplied by EZ-steer - the kit consisted of a complete upper steering column to replace the original. The supplier was completely unfazed when I asked if they did a kit for a 1917 American LaFrance which I am also rebuilding, so I would definitely speak to them about the Lagonda, although a complete column might be more challenging than it was for the E Type. Not cheap though, about $2,800 (Pounds!) if I recall. I don't have the contact details right now as I'm in the States.
Some people have successfully modified the electric steering ass.y from a modern car to fit an E Type, which would be a cheap way of doing it but a bit more work!
PS a longer drop arm will make the steering heavier, not lighter.
