i got on this kick of looking at some vintage Frams. 3 oil, one coolant filters. the first one is F1210-A. oil filter. the housing. 3 1/4 O.D. 5 1/2 tall. element no. C-1210, O.D. 2 7/8, 2 1/2 tall. center hole 5/8. number 2. coolant filter. FR 10-1, 5/8 straight aluminum casting. cant get it apart to measure the element. over all 5 1/8 tall, can O.D. 3 in. number 3. on this filter iam a little confused on the right part no. the filter i have has C-3 / C-3p2 for the element but no number for the whole housing. 6 3/4 tall, 4 in O.D. dont have size of the element. but i think it is in the books. number 4. i think F4-W is the number for the housing and filter. the label says C-4, or C-4P2 for the element. this one looks like the big brother to the C-3. this unit came with a big bracket, bolts, 2 hoses, box. i havent taken it a part to get the element no. but that info can be found in the books.
