Any NAPA dealer should be able to help. Dot has a Kralinator on the firewall made in Ont, now part of some US Co years ago. You can't buy oil canisters for vehicles 1930 and up of any brand now and in Dots past this thing was put on the firewall. Took the now back to earth filter and what was a spring mess out, then went to NAPA and plonked the thing on the counter asking for a new filter. And what is that thing they asked ? Why an oil filter canister for a 1932 Durant. What else would it be, says I with a smile ? Long and short of it was, they had books for all filters and sizes and as long as they could measure the inside, width, depth, and center tube, they can supply a filter and did. I kept the box for future part number.
