Not replaced mine yet but have on other machines. 800cc engines, any finned two-pass is better then any 8-stacked plate..any day so if it were me I would grab a 2 or 4-pass finned tube cooler the size of the old one.. with the proper ends to fit the CFM lines if possible. Otherwise get what you need to adapt. Tip- you do not want the oil to loose all it's heat. The goal is to balance the coolant temperature and the sump oil temperature as closely as possible. This balances the heat and expansion throughout the engine. The 4-pass may be overkill or too large. On other V-twins I have done the two-pass was perfect but it will depend where you are, how you ride and the air flow through the cooler. 

For visual reference this is a stacked plate cooler. Tougher then finned tube type but not as efficient :

This is a 2-pass( the number of times the tube passed through the finned area) tubed fin cooler. Radiates heat much better but the fins are susceptible to impacts:
