I have a 1989 Honda Goldwing GL 1500 and I want to build a trike. As a mechanic and welder for 37 years with the provincial government, I know that I have the skills but I am looking for advice on design and parts. Is long or short better? I am looking now for a rear end and differential. Any ideas which ones are better. I would appreciate advice from anyone whether you have built one or not. Thanks
