I did end up buying a 1953 Jubilee with a Davis 100 loader. Unfortunately no power steering. I found a kit, but for $1875 plus $75 shipping, it's a bit expensive for me. So I was wondering about if a larger steering wheel was available for the Jubilee/NAA, one larger than the OEM 17 5/8 OD. I know it should have 36 spline hub on a .75 inch shaft.

Eventually might have to spring for the Jackson kit.

Can't help with steering wheel question but, was wondering what front tires you have on the tractor?

6.50 x 16 are the front tire size on my tractor.

What I was thinking was a smoother tire helps ease the steering some. wider and smoother
