you may can find the yokes and u joint at driveshaftparts.com, i have purchased some from them and have not had any issues, also used the tractor supply yokes and u joints and so far have held up too.
i have used the mad mud motor plans but basically only used it for info on how to build shafts, the balance of the builds that we have done i looked at how the oem brands were put together and built the frame like they have
for the motor mount, skeg and cav plate we use 1/8 inch plate, weld 2 pieces of 1 inch angle on each side of the base plate for support just like go devil does
i believe the mad mud motor plans states 1/4 inch plate which is heavy for that setup
here is a link to how they turned out, scroll to the bottom of the link
