That is great to be able to get away like that. The only way I can ride one now is to have a trike and they are too expensive to build, even if I could it would have to be a chopper style trike like I use to see.
If you can fix a Dart you can build a trike.
I have been gathering parts for a home built trike. So far I have a 360 motor and auto trans out of a Diplomat cop car(yes they made them). A Jaguar IRS( made in USA, shipped to UK). A Mopar marine oil pan (thick aluminum). Aluminum slots (15X10). Harley size neck and bearings. Mufflers (Supertrapps) Cooling system with electric fans, MT valve covers,
Read and look at photos of v8 trikes, you can do it.
