Here is a pic of my assembled 260. Hopefully this helps in identifying the Gen bracket and placement.
A couple of comments in an effort to help
Your going to want to paint the bypass hose and clamps. They really stand out not painted as unoriginals
Teflon tape can at least be cut back to the edge of the exposed fitting and picked out so that the white does not remain so visible
Carb spacer would have had intake paint on it also at least towards the mating surface and fading upward
Harmonic balancer bolt and washer would not have been painted and the fuel pump gasket would not have been Felpro blue
