I converted a Cessna Aerobat to a Texas Tail Dragger.
That conversion supplied a longer flat spring main gear and the company no longer sells that kit and STC.
However if you can find their conversion it makes for a delightful little tail wheel airplane that is about half way between a Cessna 140 and a Pitts Special in its runway handling characteristics.
P.S...
I did about half of my PPL training on the Cessna 140A in 1953 which is why I used the Cessna 140 in my comparison.
I sold it to a good friend of mine who just loves it and keeps it in his hangar in Pitt Meadows.
