What exactly do you mean? Do you mean changing the Gold Spawn locations?
If so, then what I do is open MM2CT, import San Francisco (sf.psdl), create a new props list, import the gold bar object (wpobj_gold.pkg), then move it to where you want it to appear in the game. When you get it there, open up the "multicopwaypoints.csv", which is in "Race/SF". Then in MM2CT, look in the lower right corner, and copy the X,Y,Z coordinates into the file you just opened. In both the csv file, and MM2CT, the first set of coordinates is X, the second one is Y, the third is Z, and in the csv file, the forth is unused.
Do this several times until you have all of the spawn locations that you want.
If you need any more help, PM me. I can provide a more dietailed tutorial.
