MaxWedge-
Thanks for answering my question. And for clarifying how your engine weight differs from standard.
Ray-
My plan is actually to go from 16.5 inch to 15", assuming I can ever get around to it. I was simply asking MaxWedge since he has first hand knowledge of a relatively small wheel for a Healey. In my case, a 15" steering wheel will give a little more room for my legs, but hopefully not change the steering at low speeds too much. I have a spare, old, beat up healey steering wheel, which I plan to use the hub and spokes from. I found an inexpensive (new) tractor steering wheel, which is 15" diameter with spokes in the same location as a Healey's. When time allows, I just need to figure out how to safety attach the healey spokes to the tractor steering wheel. This will obviously involve removing any steering wheel plastic where the banjo spokes will attach. I then plan to use epoxy to re-create whatever portions of the tractor steering wheel were removed. A nice coat of primer and black paint will hopefully hide all of my handiwork (or not-so-handiwork in my case). If it still looks ugly, I will just get a nice leather cover to hide my poor craftsman skills. If I do ever do this, I will document it all so that others can partake later if interested.
