Double clutching is doable. Just seems synchro on 1st would make driving easier. Drivers today don't seem too understand that older vehicles like this don't handle or brake as well as what they drive. Plus I'd like to find a vintage camper to pull with it and had also heard the one with synchro in all 3 years was tougher. I've already bought the trans but may not get in a hurry to install it.
