Oil filter "stand pipe" question

Member Crackedback has posted a Wix oil filter thread. The "standard" filter for a '74 motor would be the shorter filter Wix 51068 or a "16". If you have a longer stand pipe, either the motor has been changed out or a different oil pump has been installed. Earlier slants need the longer 1 quart filter Wix 51515 or an "8" because they have the longer stand pipe. I believe 1972 was the changeover year.
