I went on Ebay tonight and found these sandcast parts for sale,
10 bolt clutch cover, left euro handgrip, push/pull throttle cables, 2 cable carbs, 16" sandcast rim with a 4 hole hub, Sandcast hiway pegs, Sandcast rear disc brake and hardware for same, several sandcast ribbed airboxes, finned tappet covers, and a sandcast 4 into 2 exhaust for only $400. I wasn't going to mention the lower 1/2 engine case but WTH.
With all these fine parts for sale it should be no problem to build one from scratch. I just realized my brothers 74 has all these parts it must be sandcast too.
