'71 Bus ball joint boots

['71 Bus ball joint boots] v A couple of years ago, I noted that all my ball joint boots are cracked and/or split on a bus that I have parked for a while. What are my options? v I *guess* they include: v #1. finding a source for just the boots. #2. replacing all ball joints [As much as I'd like to, I probably can't do that myself in near future] #3. buying 4 new ball joints and moving their boots to the old ball joints while still in place. v What do you suggest? I can't judge the feasibility of #3 from the pictures in catalogs and/or from looking at the installed parts..
