Econo king pins
 

Hi All, I'm building a 27 T using a 1966 Econo front axle. Not quite on the road yet. Just saw an add for some really neat looking kingpins for 61 to 63 econo spindles from Total Performance and wondered what the difference would be between the early spindles and my 66 spindles.

early has spacer bushings, and a differant lock bolt.
later has spacer bearings, and the lock bolt can be made to work.
a word of warning, there are problems with the lock bolt groove in some sets of pins. the groove is machined too big, allowing the pin to move in the axel. this causes premature wear in the axel itself. once the axel is worn, no way to fix it.

Thanks for the info....
