A little tad of additional information...the singletree(swingletree)that MiLo describes where you would slip the slot in the trace over the tapered end of the s'tree, then bring a thong over it and down through a hole in the s'tree(not the ONLY way to fasten trace to this type of s'tree, but the most common way, esp. in mini carts)...this type is made out of wood, and is known as a 'sword-end' singletree. You are not likely to find this type on a Bennington,
I replaced a sword-end singletree with one of a different length on a mini Meadowbrook I had once. I also used/installed the 'spring-loaded' trace keepers on that replacement singletree(got all from Witmers), and was happy with them...that said, I did not give that cart 'hard' use, so can't say how those trace keepers would hold up under severe service.
(I have the 'original' Bennington mini cart(which is somewhat larger than their latest version, which I'd order in a heartbeat IF the shipping weren't a KILLER this far away!); it has the 'curly hooks', and I've been quite satisfied with them. I LOVE the look of the newer, smaller, LIGHTER-WEIGHT Benny; hope you'll post pics of yours once you have it!!)
