Thanks for the responses. There IS a part number on the element, but it is identical to an element for my '58 apache 283 filter, that I happened to have on hand.
What has me questioning if this is the proper element, is that the tensioner spring at the top doesn't rest on the the top of the filter element like it ought to. It drops into the element and just hangs there. Either there is a washer missing, or someone has replaced it with the wrong element. This is the reason I was hoping someone here would have a part number that they were certain of.
Having the wrong element in there would not suprise me one bit. I spent two weeks jacking around with the voltage regulator/generator, until I discovered that the generator had been replaced with a ford generator. After I finally realized things were bodged up, it was really easy to throw a '54 buick generator that I had laying around on it, and then installing the right size generator belt.
