Iam building my trike using a cut apart gold wing frame. All that's left of the GW frame is the front down tubes and tubing around the gas tank. Will end up with a 45 degree rakeand the whole drive train will be on a swing arm. I have a question for all of. What is the shortest tranny that will bolt up to my 2.8 v6? Or can I just do away with the tail and use a short shaft and plate and seal?
