Trying to refurbish my buggy~ Help!

This is actually my second cart. the first was totally unsafe, no easy entry and a 2wheel. I couldnt find a 2 wheel I liked or could afford. After looking at the photo again, yes, those shafts are too short or I have him too far forward. So later may try to get some longer shafts. It is actually a smooth ride and comfortable too! I had hoped to go the Topeka Sale in April, but that is the same weekend as Hoosier Horse Fair and we will be in the breed demo ( actually hubby and his BLM Mustang)
The horse in the photo is a domestic mustang.
