Help! Does anyone know where I can get new ***** for the recirculating ball mechanism of the steering box on a 67 stang with a 1 1/8 shaft, 16:1 gear box? I got the Scott Drake rebuild kit that includes the roller bearings and the caged ball bearings. But when I got my box apart I found the recirculating ***** are rusted and pitted. (Surprisingly, the worm gear is in good shape) I've checked with local bearing supply outfits and with Ford parts. The *****, all 62 of them, are an unusual dimension (0.230 if my caliper is correct.) Nobody here has that size. This is the last thing I have to do before I hang an new suspension and and steering on the old pig after three years on jack stands. Any help would be appreciated.
