Fan pulley clearance s.b. chev

I have attached a picture of a 1985 small block 305 in my model A chassis, on the roadster pickup I am building. I have installed a short nosed waterpump, however, I am going to have to remove that humoungus stock crank pulley, and hopefully source a crank pulley that will bolt on in its place. The replacement pulley which I bolt on will have to have a v-belt groove very close to the engine side, in order for it to line up with the short nosed waterpump v-groove pulley (not shown in this picture). When I do this, the alternator will have to have the multi groove pulley swapped out for a v style pulley, and will have to move back so far that the rear of the alternator will hit the front of my valve cover, unless I change the alternator support bracket system. (the current system consists of the stock bracket plus a bracket I made which extends over to the drivers side cylinder head, because when a short nosed waterpump is bolted on, you lose a threaded hole which was in the long nosed pump.--- I need the clearance provided by using a short nosed waterpump, to fit an electric fan between it and the radiator. I do not want to spend big dollars buying special aftermarket pulleys. Does anyone have a practical solution to this dilema, as in what year and make/model might be available in wrecking yards to fix these clearance issues? Also, does anyone have a picture of their alternator support bracketry used with a short waterpump and v-style pulley? Thank you in advance for any help you can give.
