Welcome to the forum from North Carolina. The radiators are not universal. Here is a link to identify your model. Thanks for becoming a member of the forum. Be well.
1998 model is VN1500A2 (Vulcan 88). Part number is 39060-1077. Unfortunately the radiator is discontinued and will have to find a used one on Ebay or the like. Depending what is wrong with it maybe can take it to an automotive radiator repair shop.
