If it is an automatic, I have one more suggestion. Look at the torque converter bolts that connect it to the flex plate…They might be loose which will cause a "knock" at idle.
Just purchased a super '56 Ford Club Sedan and need to remove the parking light housings to fix the bulb sockets. Might anyone out there have instructions on how to do this? I have a shop manual but it has no information on removing these housings. Thanks….
