This is a common problem in older cars with idler pulleys, including Imperials (mandatory Imperial content). There is no need to spend money and time trying to find an exact replacement for the whole assembly. Unless the pulley itself is damaged in some way, the only likely problem is the bearing inside it. Any machine shop can remove the old bearing - it is probably a 203SS or 205SS, either one is available over the counter at any bearing house, which the machine shop can buy for you, or you can pick one up and take it to them to be replaced. You can do this yourself if you have tools to handle the retainers for the bearing - which are probably large snap rings or "C" rings. The bearing number is on the bearing itself - just take it to your bearing house and have them match it. NAPA stores also stock these. If they have more than one grade, take the best - it will last another 30 years.
