Vacuum advances from most any early 50's 8 cyl Delco distributor will bolt right on, but to maintain the proper advance curve you must use your old spring and shims. Even the 53-4 Packard advances can be used, as if they were easier to come by. I have used Stude, for sure, and Olds and possibly Caddy. I pick them up at flea markets whenever I see them. Once they have started to leak, death is imminent, so don't even bother to put a leaky one back on.
