Re: b-16/18/20 or h22
I have an H22 EG with Hasport mounts and the motor sits fine. Never had any problems and this is my second car with a Duce Duce in it. THe first one was a DC2. The parts are not harder to come by, if you look on ebay you can get them relatively cheap. I built mine from the ground up for a lot cheaper than probably 95% of the B-series guys.
