Search failed me, looking for the installation dimensional drawing for a Bulldog. Anyone got one they can share?

I dont have the 500 bulldog specifically but here's the 454/502 setup dimensions that can get you fairly close,,,im sure specs like the exhaust width and overall length with acc on may be different, but the major items like motor mount locations etc will be the same....
