1961/64: There are two steering column bearings and retainers.
One bearing and retainer fit into the upper flange at the top, one of each fits into upper flange at the bottom.
2) C3DZ3517A .. Bearing
2) B1AZ3518A .. Retainer.
Both these parts are available from Ford and fit Mustangs, Falcons, Fairlanes and other 1960's cars.
1965/72 columns use the same bearings and retainers, but are in different locations.
One each is in the upper flange at the top, one each is at the bottom of the column.
I don't mean to hijack any thread, but I have the same problem, cept' in the 65. Numberdummy, Do you have a diagram for the 65 f100 steering column with column shift. My steering is getting very sloppy and I noticed just below the bottom flange that the bearing ring is almost hanging out. It needs attention now. Any parts list online?
