I went to the store I get most of my automotive bits and pieces from,and asked the pimply faced junior behind the counter for an oil pack and a filter for a 302w,and he asked me what it was,,,V8,I said...oh,what year?he asked..late 60s/early 70s,,I replied...Fumble,fumble...Ahh,what sorta car is it??he asked.. 1960 F100,,I replied..Whats that?he asked...You got a chassis number??Thats no good to ya,I said..its had an engine swap....About then,I got a guy who knew me,and what I wanted...I just ask for the filter by number now...
