Can’t find anything about this specific wheel size and bolt pattern. I thought they were V860. Thanks in advance for any help. I apologize for my Newbness
V8-60s had the same PCD as their "big block" siblings; "wide five" through '39, 5.5" in '40 (if there was a V8-60 that year). The smaller Mopars have been 4.5" for decades, maybe only 3.5" width in the '30s. The cheapest Fords from '49 to ? were 16", 4.5" PCD, pretty skinny but not sure of exact width. Studebakers also have generally been 4.5" PCD.
First-generation V8-60 wheels had the 5-on-10-1/4" pattern, known as Wide-5 (1936-1939). Other Ford wheels before and after that era has a 5-on-5-1/2" pattern (1928-1935, and 1940-1949, with Mercury continuing to 1951). After that, cars went to 5-on-4-1/2".
I never got to work on any of those, that weren't "came stock" with fiberglass bodes, blown Hemis, and vintage registration, somehow.
