I believe It was Great-Planes gear I used, not the Du-Bro.... not sure anymore.

I believe it was http://www2.towerhobbies.com/cgi-bin...?&I=LXJ922&P=0 They list the width as 10 3/4" I'll confirm later.

The ground handling is more than fine. Been up for at least 15 flights since conversion, and not one ground-loop or nose-over (flying off grass). I am very happy with handling. I think putting gear behind former would be too far back, even if it was easier to install.

The spring on the sullivan tail-wheel is just pushed up into the ridder with an appropriate bend to get around the curve of the rudder. Turning on the ground is just fine.

Thanks for the compliments and all. I did not try too hard to keep the aesthetics up, but the messy parts are pretty well hidden. I really did the conversion for five reasons...
first, the control arm on the nose-wheel broke and the loc-tite on the set screw was so strong I stripped the set-screw removing it.... i.e. I broke my nose-gear.
second, the nose-wheel just has too short a moment on the plane (i.e. a tuft of grass can "bump" the plane off course on the ground... basically too squirrely)
third, the nose wheel was too flexible at times (bending sideways when trying to turn, etc. I once hit a particularly strong tuft of grass on take-off, and the nose-wheel "rebounded" into the prop. Shaved a 1/4" flatspot in to the tire... and broke the prop).
fourth, my trainer is being used by other people now (I am instructing friends/family), and they need to get tail-dragger experience before they move on.
five, I could.
